Liquid Leisure has been told it must prove it has reduced the risk of drowning before it can resume operations, the Royal Borough of Windsor and Maidenhead said. “We have served a notice banning all recreational activities associated with the lake until Liquid Leisure satisfies the council that they have appropriate and sufficient risk assessments to prevent or reduce the risk of drowning,” a council spokesman said. Emergency services were called to the park near Datchet on August 6 after the child was reported missing. About two hours later, he was found and taken to Wexham Park Hospital, where he died. Thames Valley Police said the girl’s death was not being treated as suspicious but unexplained and a file was being prepared for the coroner. The water assault course had remained closed “out of respect” for the youngster’s family until earlier this week, Liquid Leisure said. However, it has been informed that it cannot reopen yet. The council launched a health and safety investigation on August 9 “to identify any breaches under relevant health and safety legislation”. Last week, Liquid Leisure said its “thoughts and prayers” were with the child’s family, friends and everyone affected by the “desperately tragic and chilling incident”.
