It was a harrowing ordeal for a 29-year-old South Philadelphia woman who police say was raped by four men early yesterday, and then watched as her brother was kidnapped.

Her brother, Davey Robinson, 24, was later found - unharmed - near Fairhill Street and Skunk in South Philadelphia.

Capt. John Darby, of the police Special Victims' Unit, said the woman was awakened at about 4 a.m. by a ringing telephone in her home on Norwood Street near Mifflin.

It was her brother, who said that he needed money and that he was being kicked out of his house, Darby said. She refused to give him money.

After another early-morning call from her brother, there came a knock on her door. It was Robinson, looking battered and terrified, accompanied by three other men.

They forced their way inside and demanded money from the sister, Darby said. They demanded her personal-identification number for her ATM card.

While they were there, a fourth man showed up, Darby said. The first three left the house with her brother, leaving the fourth man behind.

While the three others went to ATMs with the woman's card, withdrawing a total of about $600, the man who remained in the house sexually assaulted the sister while her 12-year-old daughter and 2-year-old niece were asleep in the house.

"After several withdrawals are made by these males in the company of her brother, they then all return to the property and then the victim is sexually assaulted by all of the other offenders," Darby said.

The four men then fled with Robinson in a shiny red four-door sedan, possibly a Crown Victoria or a Mercury Grand Marquis, Darby said.

The suspects were described as men in their 20s. One had a teardrop tattoo under one eye.
