Toronto Police are trying to find the man behind four separate robberies at Queen St W and Spadina Ave.
Const. Caroline de Clouet tells NEWSTALK 1010 the first call came in at 6: 45 a.m. Tuesday.
The victims in all four cases told police that the thief had a gun but it is not clear if any of them saw it.
No one was hurt, though the victims has personal items including cash taken from them.
De Clouet says the victims all gave a similar if vague description: a man aged 20-30, with brown or black skin wearing dark-coloured clothing. In one of the instances the man was said to have a hood pulled up over his head.
