Developing--A disgruntled ex employee with Exxon surrenders after a tense stand-off with police at a New Jersey office building Tuesday afternoon.

The 63-year-old man, who was not immediately identified, turned himself in to Police negotiators after barricading himself in a bathroom or closet on the first floor of the Paramus office building.

Two SWAT teams from the Bergen County Police had set up a perimeter around the complex   just before 11 a.m. Tuesday after the building was evacuated, according to the Record of Bergen County.

The gunman is believed to have worked at a nearby Exxon gas station that keeps offices in the building.

No shots were fired and no one was injured, according to the Record.

The incident began earlier Tuesday. An employee with Prudential, which also has offices in the building, said another worker ran into his office and warned him of the gunman.

"I was sitting at my desk minding my own business. A women says, 'get out of the building.There's a man with a weapon.,'" Employee Bob Fortsch told the Record of Bergen County.

It is believed that the gunman has no hostages while as many as 100 police officers have responded to the standoff, according to the Record.
