FARMINGDALE - Nassau police are investigating after an off-duty officer was caught on surveillance camera apparently pulling his gun and pointing it at a man in a bar.

In the video from South Main Street Pub in Farmingdale, officer Ritchie Heffron can allegedly be seen taking out his weapon and pointing it directly at one of the pub's employees, Charlie Ball.

Ball says Heffron came in with a mutual friend after hours. He says the officer was drunk and became belligerent, pulling the gun as he was grabbing the men a drink.

According to Ball, three or four minutes later, Heffron pulled out his gun again, this time taking out the ammunition and placing it on the bar.

Ball say the officer was already drunk when he entered the bar, raising the question of whether he drove there while intoxicated. The surveillance video appears to show Heffron pulling up to the bar and hitting the curb.

Ball chose not to file charges. Meanwhile, Heffron has been suspended without pay and faces a disciplinary investigation. A close friend of Heffron's says he went into rehab today.
