A high school basketball coach in California was arrested on suspicion of groping a 14-year-old female student, authorities said.

Elijah Kim, 30, a junior varsity boys basketball coach at Sunny Hills High School in Fullerton, was busted about 3:45 p.m. Friday after the girl’s mother called the school to report his alleged behavior, according to the Fullerton Police Department.

Kim, who was also a substitute teacher in the district, was charged with committing lewd and lascivious acts with a minor under the age of 15-years-old, police said.

The suspect was taken to Fullerton City Jail and later released after posting $20,000 bail, the Los Angeles Times reported.

Detectives believe there may be additional victims.
