The former owner of a production company that performed at school dances all over New England has been charged with sexual assault and possession of child pornography.

James M. Holmes, 29, was arrested Wednesday morning after what police called a lengthy investigation relating to child pornography and sexual assault involving more than one child.

He is charged with two counts each of second-degree sexual assault, fourth-degree sexual assault, risk of injury to a minor and illegal sexual contact, police said. Holmes is also charged with possession of child pornography and employing a minor in an obscene performance, police said.

In April 2012, police from Plainfield, with the help of officers from Holbrook, Mass., searched the address of Holmes’ company J Productions at 54 Oakwood Blvd. No one was charged at the time, but police applied for an arrest warrant for one person. Plainfield Police Chief Michael G. Suprenant said at the time of the search that one child under 16 was assaulted at a number of locations in Massachusetts and Connecticut.

The company provides DJ and lighting services for proms, weddings, school dances and other events, according to its website.

Holmes, who now lives in Middleboro, Mass., was held with bail set at $200,000 and was scheduled to appear in court Wednesday.
