Death fears after campervan fire

Firefighters believe someone may have died in a suspicious campervan fire in South Canterbury this morning.

Emergency services were called to a reserve at Hanging Rock, about 23km southwest of Geraldine, after a passing motorist noticed the campervan ablaze shortly after 7am.

Volunteer firefighters from Pleasant Point, about 10km to the southeast, put out the blaze, Fire Service southern communications shift manager Andrew Norris said.

The campervan was completely burnt out and it was not known how many people may have been inside.

"They'll just have to sift through the debris," Mr Norris said.

The fire was being treated as suspicious.

Police and Fire Safety officers were investigating.
