A search has resumed for a man missing since a boat capsized in the River Thames.
The man in his 60s had been travelling in a small rowing boat with five other people on a stretch of the river in Sunbury-on-Thames, Surrey.
Surrey Police said it was called to Sunbury Lock at around 8.50am on Friday to reports of a small boat capsizing.
Officers attended the scene along with South East Coast Ambulance Service (SECAmb) and Surrey Fire and Rescue.
The other five people were all safely located.
A police spokesperson said inquiries to establish the full circumstances of what occurred “remain ongoing”.
“Sadly, we believe a man in his 60s may still be in the river,” the spokesperson added.
“His relatives have been informed and are being kept updated.”
A SECAmb spokesperson said on Saturday that three of the five rescued from the river were taken to hospital for further checks.
