LOS ANGELES, May 24 (Reuters) - Three weeks after a mob attacked pro-Palestinian activists encamped at the University of California, Los Angeles, police have made their first arrest in the violence, a man they say was seen in video footage beating victims with a wooden pole.

The suspect, identified as Edan On, 18, was taken into custody on Thursday in the city of Beverly Hills and booked on suspicion of assault with a deadly weapon, the UCLA Police Department said in a statement on Friday.

The man, who police said had no affiliation with UCLA, was reported by local media to be a Beverly Hills High School student.
