A man who helped save four people caught in a fatal incident in Sunbury said the death of one of the crew could have been prevented.

68-year-old Peter Lawson was swept down the Little Grey Weir near Sunbury Lock after his boat capsized and broke in two in October.

His body was found nine days later.

Chris Whiterod told an inquest at Woking Coroner’s Court on Friday that Mr Lawson may have been saved if there was an emergency system to shut the weir.

Although the inquest has ended, the verdict is expected to be given at a later date.
