SEATTLE (AP) — A youth bowling coach from the Seattle area has been charged with possessing images of child pornography that show him sexually abusing one of his team members.

Seattlepi.com reports that 53-year-old Ty Treddenbarger of Burien remains held on $500,000 bail after authorities say he admitted to abusing two teens.

The King County Sheriff's Office says a 17-year-old and his mother reported the abuse to Des Moines police March 8.

Treddenbarger is accused of sexually assaulting the boy for the last five years during out-of-state bowling trips and once at the coach's former condominium.

Authorities served a search warrant at Treddenbarger's home last week, where they say they found images of the alleged abuse on a memory card.

Other possible incidents of abuse are being investigated.
