BERKELEY — Images of three people believed to be responsible for attacks at an Aug. 27 protest at Civic Center Park were released by police Thursday in an effort to identify them.

Police believe the people in the images took part in punching, kicking and striking people at the event with improvised weapons.

Fourteen people were arrested, and some were injured as members of the militant anti-fascist group Antifa fought “alt-right” and President Donald Trump supporters.

In a news release accompanying the images, police said they were “grateful to those members of the community who provided us with the video footage which was used to capture these images,” but that the public’s help is still needed in identifying the people.

Police said “tips and leads from the public have helped identify and pursue warrants on other suspects” involved in violence at rallies and other crimes.

“Through engaged community partnerships we will continue to facilitate the free expression of the First Amendment in an environment safe for all,” the release said.
