Police have been pictured investigating a derelict garage in Dover, Kent today (March 12) as part of the ongoing probe into the disappearance of Sarah Everard.

It is understood the derelict garage, BCP Dover, had previously been run by the father of the police officer arrested on suspicion of kidnapping and murdering Ms Everard.

While police have not yet confirmed the identity of the arrested police officer, his name has been widely reported as Wayne Couzens, 48.

Murder detectives were on site on Thursday, but the search appears to have widened further to include a network of military tunnels close to the garage site.

The former family garage is located close to St Martin's Battery - a historic coastal fortification, which includes a network of underground tunnels.

It is believed the suspect had previously worked at the garage and also served in the Territorial Army before joining the Met Police.

The arrested officer, who is in the Parliamentary and Diplomatic Protection Command, was treated for a head injury sustained while in custody on Thursday. He was later discharged and returned to the police station where he is being held.

The Met later said he had sustained the injury while alone in his cell and received immediate first aid.

Ms Everard vanished while walking home from a friend’s flat in south London on March 3, with her suspected kidnap and murder prompting anger over the safety of women on the UK’s streets.

Human remains – which have not yet been identified – were found in an area of woodland in Ashford, in Kent, on Wednesday.

On Thursday night, Ms Everard’s family released a statement describing her as a “shining example to us all”, and said she had “brought so much joy to our lives”.

They said: “Our beautiful daughter Sarah was taken from us and we are appealing for any information that will help to solve this terrible crime.

“We would like to thank our friends and family for all their support during this awful time and we would especially like to thank Sarah’s friends who are working tirelessly to help.”

Ms Everard’s family also thanked the police and pleaded for people with further information to come forward.

“No piece of information is too insignificant,” they said.
