New footage shows a serial mugger hold a knife to the neck of a store clerk in one of the fifteen attacks he carried out last month - with the violent robber still on the loose.
Police say they need help apprehending a robber who is on a 'disturbing' robbery spree in Manhattan where he has mugged 11 people and held up four stores across the borough since October 9.
They have released grabs of the previous attacks in a bid to track the robber down.
The robber's MO is flashing a knife, demanding money and sometimes holding the knife to victim's necks and using physical force, NYPD Chief of Detectives James Essig said.
