Investigators with the Philadelphia Police Special Victims Unit have had a busy week working two separate cases that both involved very young females — and have made arrests in both crimes.

In the first case, officials announced Thursday afternoon that an arrest had been made in the incident of an attempted abduction of a 10-year old girl in South Philadelphia — a case that drew national attention. Investigators said that the suspect, identified as Carlos Figueroa-Fagot, 33, turned himself over to authorities late Wednesday night. The defendant has been charged with attempted kidnapping, unlawful restraint, false imprisonment, aggravated indecent assault, indecent assault, corrupting the morals of a minor, simple assault, unlawful contact with a minor and interference with the custody of a child.

The incident sparked national attention, and Mayor Michael Nutter announced a $10,000 reward for information leading to the arrest and conviction of the suspect.

The attempted abduction happened on Tuesday and was recorded on nearby surveillance cameras. The suspect allegedly tried to snatch the girl while she was walking home from a store with her 2-year-old brother in the vicinity of Porter and Lee streets. Surveillance footage showed the suspect following the children, and then walking up behind them and attempting to grab the girl from behind and pull her away. The suspect fled the scene in a white car.

In an unrelated criminal investigation, police arrested all four teens suspected of raping a 12-year-old girl at a Southwest Philadelphia recreation center Monday night.

The suspects, whose names have not been released because of their ages, are between 14 and 15 years old. They have all been charged with rape, criminal conspiracy, simple assault and related offenses. Investigators said that the victim was sexually assaulted by the four boys inside a stairwell at the Francis Myers Recreation Center at 58th and Kingsessing Avenue around 7:30 p.m. A staff member told police that he saw the assailants running from the stairwell and when he investigated discovered the obviously distraught victim.

In another unrelated criminal investigation, law enforcement authorities in Upper Darby are looking for a woman who assaulted a Pathmark supermarket security guard on Saturday and fled the scene topless.

Upper Darby Police Superintendent Michael Chitwood said the incident happened just before 1:00 p.m., when security officers at the Pathmark on 69th Street near Marshall Road caught Aishana Clayton, 26, allegedly shoplifting a package of Pampers. Clayton was stopped, detained and taken to the store’s security office. While there, she attacked a female security officer and in attempting to escape, wiggled out of her t-shirt and ran topless to the parking lot, where she got into her late model Buick and left. Police found the car abandoned on Wiltshire Road. Court records show that Clayton has four previous convictions for retail theft. She also has arrests for aggravated assault and attempted murder.

Anyone with information on Clayton's whereabouts is urged to call Upper Darby police at 610-734-7693.
