Sydney pharmacy robbed twice in two days

Police are looking for a man suspected of robbing the same Sydney pharmacy twice in two days.

A man armed with a knife entered the Little Bay shop and demanded prescription drugs on November 4, police say.

The following day the same man again demanded medications from staff members and left when they complied.

The weapon was not seen on the second occasion but staff told police they believed he was holding something under his jumper. No one was injured in either incident.
