Sudbury police are still looking for the driver of an off road vehicle that crashed into a motorcycle seriously injuring the driver. The collision took place last week in Naughton and the motorbike driver is now recovering at home. Police say the off road vehicle was speeding and being driven wildly when it hit the bike sending the driver flying. The ATV operator then took off without helping the injured biker. People passing by helped the man while waiting for an ambulance.
