MONCTON, N.B. -- A fire at a New Brunswick casino forced comedian Whoopi Goldberg to cut short a show on Saturday night.

Moncton RCMP say there was a fire in Goldberg's tour bus, which was parked at the back of Casino New Brunswick in Moncton.

Police say roughly an hour into the show, smoke from the tour bus went through the ventilation system of the casino and into the staging area.

RCMP say no one was injured and attendees were escorted out of the building as a precaution.

Police say the fire is believed to be electrical.

Goldberg was only scheduled to do one show in Moncton.
