Students at a southeast Pennsylvania high school served their detention on Saturday for taking part in nationwide walkouts last week by linking arms and wearing the names of those killed in gun violence on their clothes.

More than 200 students at Pennridge High School in Perkasie who walked out of class last week to protest gun violence were given detention.

Nearly 50 of those students served their detention Saturday, according to the The Morning Call in Allentown.

During their detention, the students linked arms, wore the names of Parkland shooting victims pinned to their clothes and sat in a circle. Flowers were placed in the center of the circle.

A senior at Pennridge said she organized the effort, saying it was disappointing the school "teaches us to be like Rosa Parks and Martin Luther King Jr., people who stood up for what they believed in."

"And they weren’t going to let us do the same," Anna Sophie Tinneny told the newspaper.

Outside the school, many community members also held up signs in support of the students.

Students across the country last week walked out of their school to protest gun violence and call for change.

The nationwide school walkouts came a month after a gunman opened fire at a high school in Florida, killing 17 people.

Several schools punished students for taking part in the walkouts.
