Police allege a bus driver had been drinking before crashing his bus Monday with a child on board.

Chatham-Kent police said a school bus left the road and hit a fire hydrant at 4 p.m.on Fifth Line in Raleigh Township.  

The lone child on the bus at the time of the collision was not injured.  Damage was estimated at $15,000. 

Officers at the scene believed the driver had consumed alcohol and gave the driver a roadside breath test. 

Police said the test revealed the driver’s blood alcohol concentration was in the "warn" range.

A 53-year-old Chatham man was charged with careless driving and issued a three-day licence suspension.

Police did not release the driver's name.
