Blue-handed vandals on the loose in NT

Blue-handed vandals are on the loose after they trashed a construction site office and spray painted it in Darwin.

Computers and air conditioners were destroyed, and the walls of the office spray painted blue, during the break-in on Thursday night.

But police expect the vandals to give themselves away.

"We believe there may be some individuals roaming around town with remnants of bright-blue paint on their hands," Detective Senior Sergeant Mark Stringer said on Friday.
