NEW YORK (CBSNewYork) – Police are hoping a sketch will lead them to the man behind a violent attack in the Bronx.

Authorities say the suspect grabbed a 68-year-old woman near White Plains Road in Morris Park and demanded money around 5 a.m. on Oct. 6.

The man then struck the victim six times with a bottle before making off with her Galaxy cell phone, a debit card, and five dollars in cash.

The woman was treated for cuts on her head and face at a local hospital.
