B.C. Sisters Left Stranded By Greyhound Bus Driver

Their tickets had expired.

VICTORIA — British Columbia's Transport Minister says reports of two young sisters being stranded midway through a bus trip at a remote Interior depot in the middle of the night is "completely and totally unacceptable.''

Todd Stone says the province has launched an investigation after a media report that the siblings, aged 12 and 16, were left for hours in Valemount after being told their bus tickets had expired.

He says the provincial investigation will involve accessing Greyhound's internal probe into the incident.

In a statement, Greyhound spokeswoman Lanesha Gipson says the girls were allowed to travel from Prince George to Valemount but the connecting bus was full and had no room to take them.

She says the driver of the second bus secured two tickets for the girls on the next bus to pass through the station.

Gipson says company employees at the 24-hour facility were aware of the situation and kept an eye on the girls until their father eventually picked them up.
