PHILADELPHIA -- A city police detective is facing kidnapping and assault charges, as well as the loss of his job, after police said he broke a man's leg and dumped him on the side of the road.

The district attorney's office said Det. Adam O'Donnell, 43, is assigned to the department's Special Victims Unit and was escorting Theodore Life Jr., 35, out of the unit's Hunting Park Avenue location on Feb. 3 when the assault occurred.

O'Donnell, a 9-year veteran of the force, allegedly got out of the sight of security cameras before he grabbed and kicked Life in the knee, causing Life to fall and not be able to stand on the leg.

Authorities said O'Donnell then used an unmarked police vehicle to transport Life to a random road in the city's Hunting Park section.

Life's father drove him to the Albert Einstein Medical Center and then Abington Memorial Hospital for treatment for a non-displaced fracture in his femur. The office said Life is left with a limp and faces ongoing treatment.

"A senseless attack on one Philadelphian is an attack on all Philadelphians," said District Attorney Seth Williams in a statement. "I also hope that by charging Mr. O'Donnell he not only understands the severity of his crime but is reminded that when law enforcement does something to clearly hurt a complainant it will not be tolerated and will be prosecuted to the fullest extent of the law."

O'Donnell faces charges of aggravated assault, simple assault, kidnapping, unlawful restrains, obstructing administration of law and official oppression.

He turned himself in on Wednesday. Police said Commissioner Richard Ross suspended O'Donnell for 30 days with the intent to dismiss him from his position.
