Sunseekers heading to the beach on the hottest day of the year have been urged to stay out of the sea after mysterious 'black and smelly' polluted sand was found.
The foul patch was discovered on Exmouth Beach in Devon on Monday morning as people headed to the south coast to enjoy blistering heatwave temperatures.
The unpleasant incident was reported at the eastern end of the otherwise picturesque beach, DevonLive reports.
