(CNN)-- The suspect arrested in the attempted abduction of a 10-year-old girl in Philadelphia turned himself in to authorities, a source with knowledge of the investigation said Thursday.
He gave himself up Wednesday, the source said, in a case that has drawn widespread attention since a surveillance video showing the attack was released by police.
Authorities say they plan to hold a press conference at 2:15 p.m. to provide further details of the arrest.
Earlier Thursday, police officer Tanya Little told CNN that authorities were questioning a man in connection with the case.
The incident sparked an outcry that reached the top levels of city government, with Philadelphia Mayor Michael Nutter announcing a $10,000 reward for the capture of the perpetrator, who tried to snatch the girl while she was walking home from a store with her 2-year-old brother on Tuesday.
"It's a sick individual to do something like that," Nutter said Wednesday at a news conference. "I want this creep off our streets immediately."
The surveillance video was released Wednesday on the Philadelphia Police Department's YouTube page.

It shows a white car pulling up to the corner of Porter and Lee streets while the girl and her brother are walking home. As the children make a left onto Lee Street, a male gets out of the car and follows the children.
The video then switches to Lee Street as the suspect walks up behind the girl and grabs her, pulling her away from her little brother, whose hand she was holding. The girl falls to the ground moments after she is grabbed and the suspect then lets go and runs away, fleeing in the white car. Authorities say the man also put his hand over the girl's mouth, though that is unclear in the video.
Police described the man in the video as a Hispanic male in his 30s or 40s who was last seen in a white, four-door, midsize car.
Neighbors told CNN affiliate KYW they are grateful the little girl is OK, but were worried for children in the neighborhood while the man was on the loose.
"It's scary. It's making people nervous, making people think that they can't bring their kids outside, you know, and let them play outside by themselves, and that's not right," neighbor Kathleen McDowell told KYW.
