''I do not know where the tourists come from but officers are pursuing them in order to protect the reputation of the area.''Officers have now interviewed staff at the lifeguard's hut on Dongtan Beach from where the pair were filmed. The couple is believed to have been drunk. Officers are now checking CCTV to retrace their footsteps in the area and appealing to the public for more information.
