Officials at TransLink are trying to figure out what caused a bus to crash into the Newton Wave Pool building in Surrey, B.C., Sunday afternoon.

The female driver of the bus -- who has more than 20 years experience -- broke her leg when the vehicle slammed into the side of the building around 1:30 p.m., lodging itself in the wall.

No one else was in the bus at the time of the crash.  People were inside the building at the time, but no one was hurt in the accident.

The bus was removed later in the afternoon after it was determined that there was no structural damage to the building.
