TORONTO - Toronto police have charged a driver with stunt driving after stopping a car reportedly clocked at about 250 kilometres an hour.

The high-performance Infiniti was stopped early today as it flew down the southbound lanes of Highway 400 in north-end Toronto. Provincial police Const. Scott Mulville says he has "never heard of a speed this high ... nothing in the range of 250 ... it's a pretty fast driver."

Mulville adds, "there's no excuse for that kind of speed."

The vehicle was impounded for a week under the province's street racing legislation and the driver faces a fine of up to $10,000.

The unidentified driver also faces the accumulation of six demerit points and will appear in court next month.
