Hamilton Police say two people were tasered and two others pepper sprayed in separate incidents in Hess Village overnight.
Officers were called to the entertainment district just after 1:30 Tuesday morning after door security at a bar reported a man in the street waving a handgun.
Police say they encountered the suspect at George and Hess streets when he took off running.
A police spokesperson says during the pursuit the suspect threw a bottle of Gatorade and hit one of the officers in the face, then he threw a loaded 9 millimetre firearm.
A 24-year-old Toronto man was tasered and arrested in the King and Caroline street area.
At the same time, a street brawl was underway in Hess village involving several women.
Two were tasered while another was pepper sprayed.
