CLEVELAND, Ohio -- The Cleveland FBI on Wednesday, along with Elyria police and the U.S. Department of Homeland Security, visited a Lorain County house where several protesters were staying in order to talk to them about their tactics outside the Republican National Convention.

The visit sparked outrage from a local group monitoring the protests, as it said law enforcement entered the house, guns drawn, in an attempt to intimidate the protesters.

FBI spokeswoman Vicki Anderson said law enforcement went to the house Wednesday morning because those inside were suspected of causing issues this week in Public Square in downtown Cleveland. Namely, agents believe the group threw bottles of urine at police officers, Anderson said.

A spokesman for Elyria police also confirmed that its officers joined the FBI at the Lake Avenue house shortly after 7:40 a.m. He did not have any further details.

Anderson said the discussion agents had happened outside the house. She said agents did not have guns in the protester's faces and did not go inside.

Nobody was arrested.

The website Countercurrent News posted an 18-minute video on its website that appears to show the encounter from outside the house. Another video posted on YouTube, which appeared to be edited at points, gives a view of what happened inside.

In the videos, law enforcement that appeared to be from Elyria police and Homeland Security step inside the front of the house and order a man out. One officer appears to go upstairs. Police officers announce themselves and at one point draw their weapons.

A law-enforcement officer can be heard yelling at one person, "get out of the bed. I'm not going to tell you again, or I'm going to come get you out of bed. Come on, you know what's going on. Get out here."

Once outside, FBI agents and police are seen on the porch and the lawn talking to people staying in the house and asking if they plan to attend any future protest rallies. They told the men in the video that others staying in the house had thrown bottles of urine at officers.

In one of the videos, one man said he woke up to police in his house with a gun in his face. Another said he told the officers several times that he did not give them permission to enter. There is also mention of police not having a warrant.

The Ohio National Lawyers Guild, a progressive legal activism organization that is monitoring the RNC, said the visit appears to have been done without a warrant. This is a problem because those inside did not give consent to search them or the house, guild leader Jacqueline Greene said.

"The Ohio NLG condemns warrantless raids without consent as unlawful police conduct," Greene said in an interview Wednesday evening, adding that her organization has not spoken to the people in the video.

She said that it seems like the visit were "for the purposes of intimidation" and that any search, if it happened, would have been unlawful.

The men in the video told agents they are from out of town and don't know everyone else who is staying there, and said they don't support violence. Upon leaving, the agents told the men to be safe. One agent apologized for scaring them.

Anderson said the agents never told anyone at the house not to protest at the convention.

She would not confirm whether agents have visited any other protests groups, but said there have been "a couple of things we have had to run down." She said it has all been done to try to keep the protests and the convention safe.

"They are welcome to protest, but it needs to be peaceful," Anderson said. "But not throwing bottles of urine at law enforcement."

In late June, FBI and local police visited the homes of over a dozen local activists to ask them about their plans for the GOP convention. The FBI characterized the visits as "community outreach." The National Lawyers Guilds and other local activists said the visits were an effort to intimidate them.
