Can you locate marked stolen items?

GUTTED: Masterton Intermediate School deputy principal Cam Maunder is asking for help from the community to recover a quad bike stolen from the school's grounds.

Thieves broke into a shed on Masterton Intermediate School grounds last Tuesday night and came away with a quad bike, two chainsaws, a welder and a full box of tools.

School caretaker Mike Clarke said the thieves got in by smashing through a lock in the middle of the roll-up shed door.

They helped themselves to a red Suzuki quad bike some time before 7am on Wednesday.

Masterton Intermediate deputy principal Cam Maunder said an identifying sign on the quad bike is a number plate labelled "Mike" that he had gifted Mr Clarke, along with yellow learner stickers.

Mr Clarke said the missing bike had thrown him "out of kilter" because he relies on it to carry his tools around the large grounds.

Also stolen were two Stihl chainsaws and a grey toolbox with many of Mr Clarke's tools in it.

Mr Maunder said the quad bike and chainsaws have invisible marker on them, which will show up under light.

Police Detective Sergeant Barry Bysouth said burglaries in schools inevitably affect children's "tools for learning".

The school and police are appealing for any information from the community.
