JACKSON TOWNSHIP — A Jackson Township teacher and basketball coach has been charged with aggravated sex assault, aggravated criminal sexual contact and endangering the welfare of a child.

On Monday evening, the Ocean County Prosecutor's Office said that 53-year-old William O'Neill of Jackson was arrested on Sunday night. He has been accused of sexually abusing a teen over a several-month span.

O'Neill has been employed as a teacher and basketball coach at Jackson Memorial High School. Authorities said a victim between the ages of 13 and 16 has said the abuse began this past summer and ended on Jan.12.

“My office was notified Saturday January 12 and Detectives from OCPO and Jackson worked on the case straight through to the defendant’s arrest Sunday night," Ocean County Prosecutor Bradley Billhimer told WOBM News.

The prosecutor's office did not say whether the victim was a student.

“I can’t comment on the status of the victim," Billhimer said. "I can tell you we are looking for any other  potential victims and that if anyone has information I urge them to call my office; Detective Stephanie Bayha 732-929-2027 or Jackson Twp. Police Detective Michael Goelz at 732-928-1111.”

O'Neill has been in Ocean County Jail since his arrest, ahead of a detention hearing.
