Jennifer Abbott, 69, was found dead in her Camden flat with tape on her mouth

A missing diamond-encrusted Rolex watch may be linked to the stabbing of a 69-year-old woman who was found dead in her north London flat, the Metropolitan police have said.

Jennifer Abbott, who was known professionally as Sarah Steinberg, was discovered fatally injured with tape on her mouth.

She had last been seen three days earlier, on 10 June, walking her pet corgi in Camden.

An ambulance crew was called to Abbott’s home in Mornington Place, Camden, at about 6pm on 13 June and she was pronounced dead at the scene.
