According to official reports, the Royal Canadian Mounted Police on Tuesday announced new restrictions on the use of stun guns following the death of a Polish immigrant.

Stun guns should be fired only when "a subject is causing bodily harm, or the police believe … the subject will imminently cause bodily harm," the RCMP said in a news release.

The order follows the October 2007 death of Robert Dziekanski, who was stunned repeatedly in a confrontation with police after he started throwing furniture around Vancouver International Airport.

The new policy also requires police to issue a verbal warning before a stun gun is fired, Canwest news service has reported. (With Inputs from Agencies)
