Winnipeg police are searching for a missing Taser after an early-morning brawl in Winnipeg's Exchange District Saturday.

Police say the Taser disappeared after they responded to the fight around 2:25 a.m. near Rorie Street and Bannatyne Avenue.

Police spokesman Const. Jay Murray said two officers were trying to help a man hurt in the brawl, but the crowd blocked them from administering first-aid and then started assaulting, pushing and punching the officers. The victim was taken to hospital in critical condition.

Officers fired a Taser, but Murray said the struggle continued, the weapon was dropped, and then stolen.

Murray said there were as many as 100 people in the area when the fight happened, but it's still not known if the Taser hit anyone during the confrontation with police. The men who assaulted the officers have not yet been found.

"We have officers out right now trying to track down exactly what happened at what point during the struggle," he said.

Murray said last night was very busy for police and only two officers were able to respond to the fight initially.

"It is quite alarming," he said.

"I think it speaks to the dangers our officers face when they attend something like this," adding backup did come after police were assaulted. The officers sustained minor injuries from the attack.

Police are warning the public someone could be injured if the weapon falls into the wrong hands. "It can cause significant injuries if it's not used properly," Murray said.

"We're just really desperately trying to get that weapon back as soon as possible so that no one's hurt by it," Murray said.

Murray said anyone in possession of the stolen weapon could face criminal charges. "It is a very serious thing to take a police officer's weapon," he said.

Police are asking the public to call them or Crime Stoppers if they have any information on the whereabouts of the Taser.
