UNION CITY - Police are investigating a home invasion in Union City last night that left a father and daughter quieted with duct tape.

Police say the father was pistol-whipped and both victims had their mouths bound with tape. A witness recorded cell phone images as police and neighbors came to their aid.

"Both the girl and him had duct tape around their mouths," a local business owner said. "So I figured he was held at gunpoint and he was beaten with a gun."

Police say the father's injuries were not serious.

Investigators are trying to find the intruders and determine a motive for the attack.
