Bangkok tuk tuk driver appears to be 'signalling' before tourists get robbed by motorcyclist

A tuk tuk driver in Bangkok looked like he was signalling before two tourists were robbed by a motorcyclist and his pillion rider.

Stomper Sarah alerted us to this video uploaded by Facebook page GOtrip on Jul 1.

Hong Kong tourist Eric Lau shared this incident he encountered, which he claims that the tuk tuk driver was in cahoots with the robbers.

Lau was travelling back to his hotel with his wife, and happened to be filming the journey.

Right before a motorcyclist drove up to their tuk tuk and snatched their bag, the driver seemed to be doing some sort of hand gesture. 

Lau says that the footage has been submitted to local police as evidence.
