A gunman opened fire in a New Jersey bar, wounding 10 people, one of them critically.

Trenton officials say police were notified of gunfire at about 12:25 a.m. Saturday outside Ramoneros Liquor and Bar. Arriving officers found several victims in and around the building.

Trenton police spokesman Capt. Stephen Varn said five men and five women were taken to hospitals, one critically wounded. Varn said an investigation was ongoing.

NJ.com reports Mayor Reed Gusciora told reporters outside the bar that he understood the gunman drove up and fired at people gathered outside the bar.

Police did not release any other information. A late afternoon news conference is planned.
