Police say anyone who steals TT signs will be dealt with 'robustly'.
The force took to social media to say a road safety sign had been removed from the Liverpool Arms Straight on the TT course.
Officers added that approximately ten other signs have been taken from the length of the coast road.
Police are warning it puts peoples safety at risk and adds further costs to the constabulary to replace them.
