TORONTO - A post-mortem has failed to show an "anatomical" cause of death for a man who died after being Tasered by Peel police last week.

Ontario's Special Investigations Unit says toxicology tests have been ordered to help pinpoint the cause, and the investigation is continuing this week.

Sean Reilly, 42, died last Tuesday less than 12 hours after being Tasered during a struggle in a cell at a Peel police station.

He had earlier been arrested "without incident" at a Mississauga home on a charge of assault with a weapon.

Reilly's family released a statement last week through their lawyer describing him as a non-violent man who was well-liked by all who knew him.

The family said Reilly was fit and had no health issues.
