PEOPLE thinking of taking a dip in the Thames are being warned to be careful.

The Port of London Authority (PLA) has taken action following the rescue of two men who sank waist-deep in mud in central London.

The pair, aged 45 and 28, were dragged from the mud near Battersea Bridge in central London.

PLA health and safety adviser Gary Davies said: "The river and its foreshore have hidden hazards and must be treated with respect.

"It is not a pleasure beach and people should not go onto the foreshore unless they have a good reason and know what they are doing.

"For example, people should certainly not go on there if they have been drinking alcohol."

If you see someone in difficulty, call 999 and ask for the coastguard.
