A body has been found in a lake following an extensive search for a woman who went missing in Cheshire on Saturday morning.

Rachel Booth was reported missing in the early hours of Saturday, police said. The 38-year-old was last seen in Sandiway at 3.50am when she was captured on CCTV at a petrol station shop, wearing black exercise clothing and trainers.

Officers, aided by police dogs, underwater search teams and Cheshire search and rescue had been carrying out extensive inquiries in the area since Booth, from Barnton near Northwich, was reported missing by her family. A body was found in a lake in a village near Delamere Forest, about three miles (5km) from where she was last seen, police said on Monday afternoon.

A Cheshire police spokesperson said: “Officers have been searching tirelessly for the 38-year-old since her disappearance. Following extensive appeals and searches in the area, officers have now sadly recovered a body in a lake in Oakmere.

“Whilst formal identification is yet to take place, it is believed to be that of Rachel. Her family have been made aware and are being supported by specialist officers.”

He said the family had asked for privacy. There were not believed to be any suspicious circumstances and a file would be prepared for the coroner, he added.

A water sports company, Wild Shore Delamere, said it had closed due to “ongoing police investigations in the surrounding area”. It said on social media: “Due to police investigations which are continuing in the surrounding area, Wild Shore Delamere will remain closed for Monday and Tuesday. We sincerely apologise for any inconvenience this may cause. The incident is unrelated to Wild Shore – however we wish to help as much as possible – so we will be closing the site until further notice.”
