A man waiting for a bus along the Bedford Highway was attacked with "sensory irritant" and robbed by two men, police say. 

They say suspects took the man's backpack, cell phone and wallet before fleeing up Hammonds Plains Road. The incident happened around 11:15 p.m. on the 900-block of the highway.

Police consider pepper spray and bear spray to be sensory irritants but didn't specify what type of substance was used. 

The victim was taken to hospital with minor injuries. 

Police are looking for two men, both about five feet nine inches tall about 175 pounds. They say the suspects were wearing hoodies, one black and one red.
