Washington (CNN) - Sen. Bob Corker said Thursday that his daughter is fine but "really sore" after being pulled from her car and thrown to the ground in a carjacking in the nation's capital Wednesday night.
The Tennessee Republican said his 22-year-old daughter, Julia, stopped the family's 2005 Chevy Tahoe not far from their apartment - just nine blocks from the U.S. Capitol building - to help someone she thought needed directions.
"A gentleman appeared, opened the door, grabbed her by the neck," the senator said. "She kicked to try to get away ... and he threw her on the pavement and drove away."
Corker credited the vehicle's OnStar system with helping to locate it, and the suspects were taken into custody a short time later in a parking lot in Seat Pleasant, Maryland.
"It's pretty incredible how quickly they were able to apprehend" the suspects, the senator said. The two people in the car were taken into custody by police in Seat Pleasant after OnStar determined their exact location and showed that the vehicle was not moving, Corker explained.
The Seat Pleasant authorities were notified by OnStar that the stolen car was in their jurisdiction, and were provided the description and tag number of the vehicle, Seat Pleasant Police Sgt. Leroy Patterson told CNN.
"The officers just searched and they saw a vehicle matching that description," Patterson said, adding that the two suspects were taken to a Maryland station to be interviewed by Metropolitan Police detectives. The Metropolitan department "will handle the actual charges, because the incident happened in Washington, D.C.," Patterson explained.
The senator praised the work of the Metropolitan Police the U.S. Capitol Police, the FBI and the Seat Pleasant Police.
He also admitted that he often thought about canceling the OnStar service subscription.
"I was telling the lady who handles that for me in Chattanooga, each month I was saying, 'I don't want to pay this, I don't want to pay this,'" Corker said, adding that it was a nominal fee.
But he kept the service, "thinking that maybe OnStar would be of some help" someday, Corker said.
"Certainly it paid off tremendously last night," he said.
