Patrol levels of old Strathmartine Hospital remain high after fire

Emergency services say they're on the look out for trespassers at the abandoned Strathmartine Hospital - two weeks after a deliberate fire ripped through the building.

Police, fire crews and members of Angus council visited the site this afternoon.

Firefighter Scott Symon said people breaking in is a growing concern.

"We've had urban explorers, ghost hunters who film on site as well as the anti-social behaviour side side where youths are setting fire's and drinking alcohol," he said.

"40 firefighters were called out to the most recent incident. It's very unsafe, there's open manhole covers.

"We want to highlight the dangers to deter people from coming out here."

Police Inspector Gary Aitken says they're still tracking the culprits.

"There's been a number of issues here in the past," he said.

"It is an area of concern for us as we do believe there have been youngsters in particular who have been entering the site.

"This potentially puts themselves at risk given the nature of the building.

"Our message would be to stay clear of the site."
