Ottawa police chief says don't jump to conclusions about deadly bus crash

Officials in Ottawa have a lot of investigating ahead after Friday's deadly city bus crash.    

The city's police chief has cautioned the public not to jump to conclusions about the events leading up to the collision that killed three people and injured a couple of dozen others.    

The double-decker bus operated by local transportation agency O-C Transpo jumped a curb and rammed a transit shelter. 

It plowed along a station platform and into the overhanging roof of the transit shelter.  

The majority of the people injured in the crash have been released from hospital with just one remaining in critical condition.    

The woman who was driving the bus has been questioned by police and released from custody.
