SPEEDBOATS, helicopters and surveillance cameras are being employed to stop tourists and locals illegally landing on mostly uninhabited islands off Shanghai.

Police helicopters plus speedboats and other vessels from the Shanghai Ocean Bureau will patrol three islands — Dajinshan, Xiaojinshan and Fushan — that are part of Jinshan District.

If intruders are recorded on eight surveillance cameras on Dajinshan or spotted by wardens there, a helicopter or speedboat carrying law enforcement personnel will be dispatched.
