Police are continuing to appeal for witnesses following the unexplained death of photographer Sussie Ahlburg at Hampstead Heath bathing ponds after an inconclusive post mortem examination.

The post mortem was carried out at St Pancras Mortuary yesterday and officers now await the results of further tests.

An inquest is scheduled to open at St Pancras Coroner’s Court tomorrow.

Ms Ahlburg’s body was discovered at about 2.30pm on Monday in the Kenwood Ladies’ Bathing Pond on Hampstead Heath.

She was 50-years-old and a photographer living in Holborn.

Ms Ahlburg went swimming in the ladies’ bathing pond on Sunday but was reported missing by her family at around 9.20pm when she had not returned home.

Police carried out a search of the local area and her body was found by divers from the Marine Policing Unit on Monday.

Detective Sergeant Trevor Plumb, of Camden CID said: “Sussie’s death is being treated as unexplained but we are keen to speak to anyone who may have seen her around the ladies’ pond during Sunday, August 4.

“Sussie was five feet 10 ins tall, slim, with greying hair, long legs, wearing a white ‘Speedo’ swimming hat, blue/transparent prescription swimming goggles, and a dark navy/black tankini.

“She would have travelled to the pond using her folding black Brompton bicycle.

“Anyone who has any information or who was in the area at the time is asked to call police on 101.”
