A Texas high school teacher who is also a church leader was charged last week with engaging in lewd conduct with boys during naked “sex parties” at his home.

Police say Jared Anderson, 28, played games with at least ten teenage boys during the parties and coerced the boys to engage in sexual acts with each other and with him, according to Fox 29 San Antonio.

Cops told the station Anderson held one party with seven boys, between the ages of 15 and 17, on Feb. 12. There was a sign on the door that said, “The last one to strip naked loses,” the station reported.

He is also alleged to have exchanged lewd texts with a 17-year-old.

Anderson was arrested Wednesday.

Up until then he was teaching English at Judson High School in San Antonio. He was also group leader at a local church, Fox 29 reported.

Police declined to say if any of the alleged victims were his students.

The parents of some of the boys showed detectives apologies Anderson allegedly sent to them in texts, the station reported.

“This all stems from a report that came in a few days ago where two victims presented themselves over at one of the substations and reported that this individual had hosted them for some parties at his house,” San Antonio Police Sgt. Jesse Salame told the San Antonio Express-News.

The paper reported that police believe the number of alleged victims may be more than the seven to ten who have been identified.

Anderson was jailed on two counts of sexual performance of a child and one count of indecency with a child. He was being held on bail totaling $150,000.

Jail records did not identify his defense attorney.

The Judson school district placed him on administration leave. He became a teacher more than two years ago.
