PHILADELPHIA (CBS) — Philadelphia police are now looking for a man as well as a woman in Monday’s mysterious abduction of a five-year old girl from her school.

Captain John Darby of the Special Victims Unit says the girl, who was found Tuesday morning in Upper Darby clothed only in an adult t-shirt, has been interviewed. Darby said the victim told them a second suspect was involved. (Read Related Story)

“We have a second adult, a male adult, we know was involved in the situation. He was in that house,” Darby said.

The house to which the girl was walked after being checked out of Bryant Elementary school by a woman in face-shrouding Muslim garb. She is described as a black woman with light or greenish eyes, late 20′s, 5″ 5′ to 5″ 8′ and possibly pregnant. The man is described as a light-skinned male, possibly white, with short brown hair.

Darby says police are focusing on the blocks around the school.

“This is a target area. It may expand beyond that. We’re going by an account by a five-year-old basically indicating she had only walked a couple of blocks.”

Darby says he hopes community members are outraged enough to give police some tips.

There’s now a $10,000 reward; $5,000 for an arrest and another $5,000 for an arrest and conviction.

Anyone with information is urged to contact the Special Victims Unit at 215.685.3251/52/53.
