The Ann Arbor Pioneer varsity baseball coach was arraigned Thursday after allegedly using the internet to arrange a date to have sexual relations with an underage child.

Macomb County Sheriff's Office arrested Gerald Holley, 57, on Wednesday after undercover detectives, disguised online as a child, began conversing with him and arranged a meeting.

Holley is employed as a biology teacher and coach at Pioneer High School in Ann Arbor, according to a news release from the Sheriff's Office.

According to the school's website, Holley has been the baseball varsity head coach at Pioneer since 1995.

"Gerald Holley is an employee at Pioneer High and is on administrative leave," said Jeanice Swift, Ann Arbor Public Schools superintendent, in a statement.

The school district declined to comment if Holley was suspended with pay but said Pioneer High parents have been notified.

Holley was charged with three felony counts of child sexually abusive activity and one felony count of using the internet to communicate with another to commit a crime. Each count carries a maximum penalty of 20 years and the computer crime carries a maximum penalty life.

Holley was arraigned in 41-B District Court in Clinton Township on Thursday. Bond was set at $50,000 and if he's released, he is ordered to home confinement on a tether. He will return to court for a probable cause conference at 1:30 p.m. Oct. 25.

"As often occurs in cases such as this, this man pursued a career which surrounded him with young people," stated Macomb Prosecutor Eric Smith, in a press release. "I urge parents to remain vigilant of all those who supervise their children, even longstanding 'authority' figures. The predators are out there, and they make it their business to get right next to your kids."
