Police say the woman approached the suspects near Chrystie and Grand streets at about 9:30 p.m. April 15 and asked for help finding her way.
One of the suspects gave her directions and started walking with her in the direction she needed to go. The second suspect followed them, grabbed the woman from behind and pinned her against the wall.
The suspect who had initially been walking with her started punching her in the ribs and on her thighs, then sexually abused her and stole her property before running off.
Authorities released a sketch of the suspect accused of sexually abusing the woman (above).
Anyone with information about the suspects is asked to call Crime Stoppers (800)-577-TIPS.
