TWO tyres dating back to a 1930s car, old milk bottles and a pushchair - retrieving these items from a lake was all in a day's work for scuba divers from Potters Bar.

Members of the Potters Bar Sub Aqua Club had been called in to clear the murky waters of the Serpentine in Hyde Park, central London.

Their mission was to make the lake safe for competitors in last weekend's Dextro Energy Triathlon ITU World Championship Series.

The areas in front of the diving and exit pontoons had to be cleared to avoid injury to the swimmers.

Jeff Dixon, the club's diving officer, said: "The visibility was very poor and special rope techniques had to be used both to stay in touch and for safety purposes.

"Despite the unpleasant conditions everyone did their job and the exercise was successful in all respects.
