WARSAW, Poland - Canada's ambassador to Poland expressed "deep sympathy'' to a Polish Foreign Ministry official on Monday over the death last month of a Polish immigrant shot by a Taser stun gun, a ministry spokesman said.

Ambassador David Preston discussed the issue with Andrzej Jasionowski, the head of the consular section at the ministry.

"The ambassador expressed deep sympathy and said that this tragic accident was the subject of an investigation,'' ministry spokesman Piotr Paszkowski said by telephone.

"He said it was in the interest of both sides to present the results of the investigation without delay,'' Paszkowski added.

Jasionowski asked that the findings be made available to Polish authorities and passed to Preston all information available at present to the Polish side, he said.

Robert Dziekanski, 40, arrived at Vancouver airport Oct. 14. It was his first flight, and was to be the start of a new life with his mother in British Columbia.

But Dziekanski, who spoke only Polish, began acting erratically at the airport. He may have became upset when he didn't see his mother in the secure baggage area.

He spent hours in the area, didn't get the help he needed, while outside the area his mother, Zofia Cisowski, was in vain asking for him.

Police were called in and used a Taser on Dziekanski in an action captured on video by a witness.

The video shows officers zapping a distressed Dziekanski twice, less than 30 seconds after encountering him. They then physically subdued him on the floor. Dziekanski died at the scene.

An investigation is underway into what caused Dziekanski's death and a coroner's inquest is planned.
