FONTANA – Police Thursday arrested a Fullerton man after he allegedly sexually assaulted a 14-year-old girl with whom he had allegedly been conversing via social media and other means, police say.

Benny Kim, 20, was arrested on suspicion of sex with a minor and related charges, according to San Bernardino County sheriff’s booking records. He was booked at West Valley Detention Center where his bail was set at $100,000.

According to a Fontana police news release, a joint investigation between the department’s Internet Crimes Against Children Task Force and Fontana Unified School District police allegedly revealed that Kim had been conversing with the teen over social media sites, in texts and on the phone.
