Police have arrested one person for impaired driving after a single-vehicle crash in Kitchener on Wednesday.

It happened near the intersection of Highland Road East and Spadina Road East before noon.

The car flipped and left the roadway, ending up on its roof in the snow. Officials said that the driver, a male whose age wasn't released, was arrested.

"My husband and I were just getting up, having our coffee and we just heard a very big bang, looked out our window and oh my God," witness Carolin Rowden said.

Joshua Frank said he was on his way to work at 10 a.m. when the crash happened. He said it pinned a woman walking to a nearby fence.

"Her arm was pinned up against the fence," he said. "I went and ripped the board, got her unstuck." Frank said she was treated at the scene by paramedics.

Police have not said whether anyone was hurt in the crash, but said they would like to check on the wellbeing of a female passenger who fled the scene. A K9 unit started a track to find her but she remains outstanding.

She's described as a white woman in her late 20s who had blonde hair. She was last seen heading east on Spadina and was wearing glasses and dark clothing.

The road was closed while crews towed the vehicle away but has since reopened.

Anyone with information is asked to contact police.
