London police say a 29-year-old woman has been arrested after a crash between a vehicle and a car that sent a motorcyclist in hospital.

The crash between a Pontiac Pursuit and a motorcycle took place at Gladstone and Russell avenues around 8:30 a.m. on Thursday.

According to investigators, the westbound car failed to obey a stop sign and a southbound Harley Davidson collided with the passenger side.

The 50-year-old motorcyclist was transported to hospital with serious injuries.

Police say the 29-year-old driver of the vehicle - who was treated at the scene for minor injuries -  was arrested on the suspicion of impaired driving by drug.

Reconstruction officers spent several hours at the scene and police say charges are pending
