U.S. Capitol police arrested at least 80 people Thursday who were demonstrating Thursday against the proposed Republican health care bill.

In a statement, police officials said they responded to 13 locations in office buildings on both sides of Congress beginning about 2 p.m.

Twitter feeds filled with videos and images of demonstrators who were cuffed and flanked by police as some yelled through the hallways in protest of the bill.

“After officers arrived at the numerous scenes, they warned the demonstrators to cease and desist with their unlawful demonstration activities,” the statement said. “Those who refused to cease and desist were placed under arrest.”

Police said the arrested were charged with “Crowding, Obstructing, or Incommoding. “

Officers arrested 10 men and 11 women at House Office Buildings, while 22 men and 37 women were arrested on the Senate side.

Officials did not identify which Congressional offices had been targeted.
