Police are looking for a man wanted in connection with a string of robberies in and around Manhattan.

Between last Wednesday and Monday, investigators say the man in this video has struck four times.

Police say the robber went to the Nature's First Pharmacy off of First Avenue and East 18th Street shortly before 11 a.m. Monday.

They say he approached an employee, went behind the counter, and told her he had a knife.

The NYPD says in the other incidents he targeted a different pharmacy, a dry cleaners, and a bank.

The suspect is described as being in his 40s and about 5-feet-8-inches tall.
