Police searching for sex assault, armed robbery suspect

Philadelphia Police released a sketch of a man wanted in connection with an early morning sexual assault and gunpoint robbery last Thursday in North Philadelphia.

Police said a 20-year-old woman was walking around 4 a.m. when she was approached from behind, and forced at gunpoint into an alley on Park Avenue near York Street.

A man police say is between 25 and 30 years old used articles of clothing to tie the woman's hands and feet and sexually assaulted her before taking her purse, which contained an undisclosed amount of cash, a cell phone and identification cards among other things.

Police said the man is black with a medium complexion, about 5-feet-7 with a thin build. The man was wearing blue jeans and a dark shirt at the time.
