Toronto police are investigating a collision involving a TTC bus after the vehicle struck a utility pole in Flemingdon Park early Thursday morning.

There were about 10 passengers on the bus when it ran into the pole on Overlea Boulevard near Thorncliffe Park Drive at about 1:30 a.m. None were hurt.

Significant damage could be seen near the front passenger doors on the bus' right side. The glass in the doors appeared broken in several places.

The impact from the bus tore out the hydro pole at its base. Crews could be seen working to secure the scene shortly after the crash.

Police say they don't plan to charge the 41-year-old male driver, saying he is not suspected of being impaired. The driver suffered minor injuries in the crash and was taken to hospital for medical tests.

The investigation has been handed over to the TTC.

On Aug. 30, another TTC bus collided with a crane truck on Lawrence Avenue East, near Don Mills Road, killing 43-year-old passenger Jadranka Petrova. Thirteen other passengers were injured in the crash.

A small quantity of drugs was found among the belongings of the bus driver, but a drug test was not administered after the crash and police say there was no indication the 52-year-old driver was under the influence.
