The police officer detained over the disappearance of Sarah Everard has been arrested on suspicion of murder.
The man, who has not officially been named, is aged in his 40s and has been serving in the Metropolitan Police’s Parliamentary and Diplomatic Protection Command, report says.
He was arrested on Tuesday evening on suspicion of kidnap and has now been further arrested on suspicion of murder and a separate allegation of indecent exposure.
A woman in her 30s remains in custody after being arrested on suspicion of assisting an offender.
A spokesperson for the Metropolitan Police said the suspect’s primary role was uniformed patrol duties of diplomatic premises.
“Officers are searching locations in London and Kent including a property in Deal and an area of woodland near Ashford,” a statement added.
“Following the arrest of the police officer, the Metropolitan Police has made a referral to the Independent Office for Police Conduct.”
Nick Ephgrave, assistant commissioner of the Metropolitan Police, previously called the officer’s arrest “shocking and deeply disturbing”.
“I understand there will be significant public concern but it is essential that the investigative team are given the time and space to continue their work,” he added.
Sarah Everard, 33, disappeared last Wednesday while walking home from a friend’s house in London.
She left the property in Leathwaite Road, Clapham, at around 9pm through a back gate and started walking along the South Circular towards Brixton.
Sarah Everard is thought to have walked across Clapham Common and was expected to arrive home approximately 50 minutes later, but has not been seen or heard from since.
The last sighting confirmed by police was of Ms Everard walking along Poynders Road, from the junction with Cavendish Road, at around 9.30pm.
Investigators have been asking people who live in the area, were there around the time or may have dashcam footage from vehicles to come forward.
Officers have been combing through CCTV and visiting hundreds of homes looking for potential evidence.
The property being searched in Deal is believed to be the suspect’s home, where witnesses reported police had dug up the garden.
A neighbour in the road said a police officer lives at the address with his “chatty” wife and two children.
The land near Ashford is a disused outdoor activity and golfing centre near the village of Great Chart.
Downing Street said the prime minister’s thoughts were with Ms Everard and her friends and family.
