UPDATE 1-Canada police officer defends repeated Taser jolts

(Updated throughout)

VANCOUVER, British Columbia, March 2 (Reuters) - A police officer who repeatedly shot a Polish immigrant with a stun gun in a fatal incident at Vancouver's airport acknowledged on Monday his report on the incident had errors in it.

Royal Canadian Mounted Police Constable Kwesi Millington said he never imagined that the incident would result in the death of Robert Dziekanski, although training in use of the Taser guns warned about repeated applications of the weapon.

Millington told a provincial public inquiry that he initially used the weapon because Dziekanski showed "an intent to attack", and fired again almost immediately because he did not fall to the ground after the first 50,000-volt jolt.

A video of the incident played during the inquiry appears to show a screaming Dziekanski falling to the ground before the second shock is fired. He was eventually shocked with electricity five times.

Millington acknowledged that after watching the video there were mistakes in his report initially after the incident in 2007, including his statement that Dziekanski had lunged at the four police officers and had to be wrestled to the ground.

"There are errors in it, yes," Millington said.

Dziekanski, who was in the process of immigrating to Canada where his mother lives, died during the struggle with police although the exact cause of his death has never been determined.

A video of the October 2007 incident received international publicity and raised controversy over the police use of the electronic weapons that are intended to disable victims as a safer alternative to firearms.
