Arrest made in assault on LAPD officer at May Day rally

The LAPD says that Brian Mendoza, 23, has been arrested in the videotaped head bonking of an officer working the May Day rallies in downtown. Mendoza was booked on suspicion of assault on a peace officer, a felony, and was being held without bail. He was described as a transient who frequents Skid Row and who is on probation for earlier assault on a peace officer in El Monte. The assault, along with another on a line of officers by protesters wielding a wooden pallet, was caught on video tape and widely distributed. Police Chief Charlie Beck had called for the public's help in identifying the attackers.
