A 29-year-old man has drowned in Shadwell Basin while enjoying the sunshine with his friends.
The man, who has not been named by police, jumped into the basin at Wapping when he was with two of his friends at around 1pm on Wednesday, July 20.
But he failed to surface and emergency services arrived at the scene to assist the man but the crowd saw a police diver pull out his body.
Dominic King, 36, who lives nearby, said to The Evening Standard: “It was packed. There were about 100 people still there jumping in and swimming.
“There were two little kids swimming about 30 seconds away and the police told them to get out.
“A diver went in for three minutes and came back with his body under his arm. Police officers dragged him up and medics rushed over and administered CPR but I knew - he’d been under for 20 minutes. It’s so sad.
“But even as they carried him out there were still people swimming nearby. It’s beautiful but it’s dangerous. What a waste of life.”
The unidentified man is the second to have drowned in London during the summer heat, after 21-year-old Leon Wilson died near Staines in West London.
The Royal Lifesaving Society has urged the public to cool off at safe lifeguarded areas to avoid similar tragedies.
