A 94-year-old woman is dead after a police chase in Brantford ended in tragedy Monday.

The provincial police watchdog is now investigating, and probing the circumstances that lead to the chase and eventual crash.

According to the Special Investigations Unit, Brantford police officers were searching for a man wanted in connection with an assault with a weapon Monday morning. In a media release, Brantford police said the man was a suspect in a stabbing.

The SIU says the officers tried to stop a vehicle just after 10:30 a.m., when it took off.

The vehicle then collided with another car at the intersection of Colborne Street and Gilkison Street, the SIU says.

The driver of the car that was struck wasn't injured, but one of the passengers, a 94-year-old woman, was rushed to hospital, where she was pronounced dead. Another passenger in that vehicle suffered serious injuries, including several broken bones, the SIU says.

Investigators say that there were two people in the vehicle that fled. One was treated for minor injuries, while the other wasn't hurt.

Brantford police released a statement saying the man who was wanted on a warrant was arrested, but they did not specify on what charges.
