A brutal beating was caught on video at a Riverside tobacco shop and police are now hoping a tipster can identify the alleged attacker.
The unidentified man walked into Smoke Shop Plus on Tuesday about 12:30 p.m. and allegedly struck a female store clerk on the head several times with a hammer or mallet.
The man, possibly a transient according to police, then raided the cash register and fled the store on foot.
The 52-year-old victim was taken to Riverside Community Hospital in serious condition. She owns the store, located at 1788 University Ave., with her husband.
Anyone with information about the attack was asked to contact Riverside police at 951-826-5700.
