Cops in New Jersey came under fire this week for allegedly harassing fellow officers and employees with a large blue dildo, dubbed “Big Blue” — and now there’s a video that shows it.

Footage obtained by NJ Advance Media on Thursday shows the accused lawmen, Lt. Thomas Murphy and Det. Sgt. Andrew Huber, of the Mountainside Police Department, using the sex toy to allegedly pick on a male dispatcher.

With Murphy looking on and filming, Huber appears to smack the department employee in the face several times with Big Blue before placing it inside a filing cabinet.

“What’s that? A f–king dick?!” shouts the dispatcher. “What are you, taking a picture?I”

The alleged “attack” may seem like like fun and games between the boys, but not to five Mountainside cops and one female department worker — who have decided to sue.

In their complaint, the group claims that they experienced a “hostile work environment” due to Murphy and Huber’s actions. The pair allegedly subjected their fellow officers to Big Blue “on almost a daily basis” — along with forced tickling, “ramming” a flashlight up their fully clothed backsides, and even flashing their testicles and placing them in people’s food.

Additional video obtained by NJ Advance Media on Thursday purportedly shows Murphy — dressed up as Santa one year for Christmas — handing out “gifts” to Mountainside cops.

“Santa wanted to give you something special this year,” he says, before whipping out a flesh-colored dildo. “Santa wanted to give you a brand new penis!”

Huber and Murphy are both currently on paid administrative leave as a result of the suit.
