A North Attleborough man who coached swimming at an area high school as well as a YMCA and private swim club has been arraigned on possession of child pornography charges.

Timothy Kelly was released on $75,000 bail after a not guilty plea was entered on his behalf Tuesday in Taunton District Court.

Prosecutors allege the 38-year-old Kelly had sexually explicit images of children on his computer as well as on DVDs in his apartment.

The Sun Chronicle of Attleboro reports that Kelly was the swim coach at North Attleborough High School, aquatics director at the Attleboro YMCA, and a swim coach at the Bearcroft Swim Club.

Police say there is no evidence that local children were harmed.

Kelly's lawyer says his client is cooperating with authorities.
