Detectives investigating a fire in which a woman died have released the image of a witness they want to speak to.

The CCTV still shows a man in the area around the time of the fire at a block of flats in Daleham Gardens, Camden.

Eight fire engines and 60 fire fighters tackled the fire just before 2am on November 21 with the building’s roof and second and third floors gutted by the flames.

About 20 people fled from the block of 11 apartments, owned by Camden Council, before the emergency services arrived. The fire was brought under control by 5am.

A neighbour, whose home backs onto the site of the blaze, told the Ham&High after the fire: “I woke at 2am and my bedroom was full of smoke. The smoke was so thick I assumed it was in my house.

“Then when I looked out of the window I saw the house on fire. It is so sad that somebody has died.”

Magdalena Fink, 35, was pronounced dead at the scene of the blaze.

Ms Fink, originally from Sendenhorst, Germany, was a UK resident. Her next of kin have been informed.

A post-mortem examination on December 1 at St Pancras Mortuary failed to identify a cause of death with the results of further tests to come.

The cause of the fire has yet to be established although police confirmed it started in a cupboard in a shared basement.

On the image’s release, Det Insp Tom Kearney said: “We are keeping an open mind as to the circumstances of this tragic incident and still trying to discover the exact cause of the fire. For this reason we are appealing for anyone with information to contact police.

“We are also releasing a CCTV image of a man who was in the area around the time of the fire.

“We would ask this person, or anyone who knows or recognises them, to contact police.

“This man could have vital information that could assist the enquiry,” he added.

No arrests have been made. Enquires continue by detectives and London Fire Brigade investigators.
