The suspect, dubbed the Preppy Masher, is accused of groping and thrusting himself on at least four victims who were shopping at stores in Canoga Park and Woodland Hills.
Police said Alon Lerner, of Winnetka, surrendered when he came into the LAPD Topanga station Friday afternoon. Tips from the public came in overnight, authorities said, after they saw photos of the suspect on the news.
Lerner was booked into Van Nuys jail on suspicion of felony sexual battery. His bail is set at $65,000. Authorities said Lerner has no prior criminal history.
