Vancouver police have made an arrest following a series of unprovoked assaults last month.
Police issued a warning last week and released surveillance images of a suspect who allegedly approached and punched, elbowed or pushed a stranger on four separate occasions in public places and then walked away.
They say 39-year-old Colin Akwei of Coquitlam was arrested Wednesday following a tip from the public.
Investigators are trying to determine a motive for the assaults.
