A 22-year-old nursing assistant who was abducted on a Philadelphia street over the weekend has been found alive, and her kidnapper is in custody, police said Wednesday.

Carlesha Freeland-Gaither was discovered in Jessup, Md., after she was abducted around 9:40 p.m. Sunday and forced into a four-door vehicle. Authorities were able to track the vehicle, Edward J. Hanko, the special agent in charge of the FBI's Philadelphia division, told reporters at a press conference Wednesday night.

Freeland-Gaither's alleged captor, Delvin Barnes, 37, was apprehended by a team of U.S. Marshals and ATF and FBI agents. He already had an outstanding warrant for attempted murder and other charges from the Charles City County sheriff's office in Virginia, and will face additional federal crimes in Philadelphia, authorities said.

Authorities, citing the ongoing investigation, did not disclose the exact circumstances that led to Barnes' capture or details about Freeland-Gaither's rescue.

Freeland-Gaither had minor injuries and was taken to a local hospital but was talking with authorities and had already spoken to her mother.

"The bottom line is this: She's been returned home safely, this individual is off the streets and no one else is in danger right now," Philadelphia police Commissioner Charles Ramsey said.

Freeland-Gaither had been last seen on surveillance video being grabbed by a man and pulled toward a car Sunday night as she struggled to get away in Philadelphia's Germantown neighborhood.

Police and federal authorities had released a stream of images over the past two days from surveillance cameras in Maryland and from a Philadelphia supermarket hours before the abduction.

The 22-year-old nursing assistant graduated from high school in Maryland and lived with her grandfather in Philadelphia until a couple of months ago, when she moved in with her boyfriend.

Her grandmother Ana Mulero says she has worked with cancer patients and has been pursuing a career in nursing.

Federal agents aiding in the multi-state search for her had released supermarket security video of a man they said was a person of interest.

The video showed a man in a knit cap and dark coat walking down an aisle of a Philadelphia store and using a self-checkout station. A timestamp indicates the video was recorded eight hours before Freeland-Gaither disappeared
