A jury returned a guilty verdict Wednesday on aggravated assault charges against Michael P. Pfrommer.
Authorities said Clayton police officer Stanley Williams was tackled when he responded to a domestic-violence incident at Pfrommer's home in September 2006.
Pfrommer faces a maximum of five years in prison, officials said. Superior Court Judge M. Christine Allen-Jackson revoked Pfrommer's $2,500 bail. He will remain in Gloucester County Jail until he is sentenced on April 4.
