A teenager who took police on a wild chase as he raced a stolen truck through southwest Calgary last month has pleaded guilty to dangerous driving and four other charges.

The 15-year-old boy, who cannot be named, led police cruisers and a HAWCS helicopter through city streets for over an hour.

The teen sped through red lights, swerved around other vehicles and drove over a median into oncoming traffic as police pursued him.

Three police cars were damaged during the chase. Police finally boxed the teen into an alley and arrested him.

On Friday the teen pleaded guilty to five criminal offences including mischief, dangerous driving and possession of a stolen vehicle.

"He's taken responsibility for his actions," said the boy's defence lawyer Kathleen Reyes.

Crown and defence lawyers said they are waiting for the results of a pre-sentence report to determine what kind of sentence they will ask for.

"The reports often tell us a story we didn't know," Reyes said.

The boy’s father and step-mother were in court but made no comment.

Officials said it was remarkable no one was injured or killed.
