Emergency services have responded to reports of a couch being set alight at an abandoned hospital in Mornington.
A police spokeswoman said officers responded to reports of wilful damage at the Glamis Hospital site in Montpellier St about 2.30pm.
Fire and Emergency New Zealand Senior Station Officer Mark Leonard, of Dunedin City Station, said crews found a chair and couch on fire in an exposed area under the house.
It was believed to be deliberately lit, SSO Leonard said.
It was a dangerous building which put crews in danger, SSO Leonard said.
Three fire engines and police officers attended the callout.
