A $300,000 arrest warrant was issued after Orinda resident Joel Kaufman vanished earlier this week.
The 52-year-old turned himself into the Martinez Detention Facility around 11 a.m. Friday. He was booked for two counts of lewd and lascivious acts on a child, sexual penetration, annoying or molesting a child, and invasion of privacy.
Kaufman owns Triple Play Batting Cages in San Leandro. He is the head coach of California Smoke Baseball Club, a travelling high school club. He also coached at Bishop O'Dowd High School between 1999 and 2005.
The Oakland Diocese said Thursday that no parents have come forward to say their son was abused, but police think there could be more victims.
Police are asking anyone who knows anything or who may have been a victim to please come forward.
Kaufman is currently in jail. His bail is set at $325,000.
