The high school students who organized a public protest Monday have disputed a Portland Public Schools message to parents that included a police warning about "outside groups" trying to influence students.

The protest -- part of a series of demonstrations that have roiled the city since Donald Trump's election as president -- drew a crowd of about 100 students who marched from Northeast Portland to downtown.

Police arrested three organizers of local activist group Portland's Resistance who accompanied the students on the march. The Resistance has been at the heart of the anti-Trump protests since they began here. Police declared one of the protests a riot after a group of agitators in a crowd of thousands started smashing cars and businesses along the route. More than 100 people have been arrested during the demonstrations.

The student statement, signed by Grant High School students Callie Quinn-Ward, Dylan Palmer, Finn Hawley-Blue, claims they initiated contact with the activist group and asked for help in planning and spreading the word.

Instead, Police Bureau officials "fabricated their own narrative," students said in an email Tuesday morning.

"They claimed outside groups were prompting students to get involved in dangerous protests. This is a lie that was seemingly meant to discourage youth from participating in a nonviolent demonstration," they said.

"Our district, Portland Public Schools bought into this falsified narrative. Despite clear information and numerous sources saying that our event was peaceful and created by students, they sent out a message to all district parents encouraging to keep their students away from the protest."

The school district on Sunday sent out a message to parents of middle and high school students.

"We want to notify you that our partners with the Portland Police Bureau approached us with concerns that there are some outside organizations encouraging students to participate in additional protests this week," the school district said. "The police are concerned about the safety of our students if they join any of these outside organizations in their demonstrations. We encourage open debate and dialogue, but in a non-violent manner."

Here's what the full statement said in response to public school and police officials:

Portland Student Solidarity Protest Official Statement

Tonight, on November 21st, 2016, we organized a protest for students across the Portland metro area to show solidarity in the wake of the election. Our message was one of peaceful resistance and empowerment. We spoke about long-term involvement, our generation's message and announced a new potential group.

This event was both created and organized by Portland high school students. We decided to reach out to local organizations to assist us in planning and spreading the word of the event. Two organizers from Portland's Resistance, Gregory McKelvey and Kathryn Stevens, kindly agreed to help. They provided advice when needed and helped amplify our voices. However, the protest remained a youth-driven action.

Yesterday, the Portland Police Bureau fabricated their own narrative. They claimed outside groups were prompting students to get involved in dangerous protests. This is a lie that was seemingly meant to discourage youth from participating in a nonviolent demonstration.

Our district, Portland Public Schools bought into this falsified narrative. Despite clear information and numerous sources saying that our event was peaceful and created by students, they sent out a message to all district parents encouraging to keep their students away from the protest. Instead of letting their own students' voices be heard, they allowed police propaganda to take control. As a result, parents became hesitant in letting their students attend and our turnout diminished.

Following a powerful rally at Holladay Park, we took to the streets to march. Although our group consisted nearly entirely minors simply showing solidarity and resistance in a peaceful manner, police aggressively blocked roadways and attempted to intimidate us. Still, everyone exemplified restraint and no violence or destruction of property took place.

It was clear from the start that the police were singling out Greg and Kat. We witnessed them pushing the two around and trying to separate them from the group. Police also rammed their bikes and motorcycles into us, threatened us, hit and pushed us, ran over our feet and yelled in our faces. Meanwhile, the Portland Police Bureau was tweeting their concern for the safety of students. Do not let them tell you they were protecting us tonight. The only real "danger" we experienced tonight were the actions of the police.

This all came to a climax when cops deliberately separated Gregory and Kathryn from our march as they were doing nothing but supporting our peaceful demonstration. A large police officer pinned Greg down and put him in handcuffs. Meanwhile, as Kat was hugging Greg, the police grabbed and threw her onto the ground. Male police officers pulled and twisted her arms and began violently touching her and ripping off her jacket. She screamed in pain and shouted arequest to be patted down by a female officer, but the male cops ignored it and continued to violate her. It has later been reported that Kat's hand was allegedly broken during the arrest.

The scene left many of us in shock. Although we recognize that this type of brutality occurs every day, especially to people of color, seeing this unprovoked violence unfold firsthand was a new experience for many.

Soon after, we headed to the police station to show our solidarity for those who were arrested. We sat on the curb in front of the station as officers chained the doors shut. They took pictures and selfies of us as they laughed and grinned with glee. These cops, Officer Taylor and Officer Tyler found the violent suppression of free speech to be a laughing matter. As our protest ended and students began to walk away, the police grabbed a final victim, known activist Micah Rhodes who was simply walking on the sidewalk peacefully, and put him under arrest.

Tonight's events are unacceptable. What occurred were planned-out, tactical arrests. Now, Kat, Greg and Micah are being held as political prisoners. This is police tyranny. It is an unsuccessful attempt to drown out the voices of students who are scared of this clearly oppressive police bureau and government. Portland Public Schools and many media sources are only covering up the police's abuses by furthering the false narrative of Greg, Kat and Micah being outside agitators encouraging students to unlawfully protest.

We, as students, refuse to be silenced. We stand with tonight's arrestees and pledge to do whatever we can to support them. We call on Portland Public Schools to consider whether they want to continue to take the side of an oppressive police bureau or stand in solidarity with their students and staff attempting to make our schools safe places for all. We ask that the media report truthfully from all perspectives and not be swayed by false accounts of events. We demand that the Portland Police Bureau drop all charges against Gregory McKelvey, Kathryn Stevens and Micah Rhodes and examine who it is they truly serve and protect.

We will not be intimidated. We will continue our fight against bigotry. We will resist.

- Callie Quinn-Ward, Dylan Palmer, Finn Hawley-Blue and other student organizers
