A pensioner known for carrying a teddy bear and walking her dog around Camden has been named by police as the woman killed after being hit by a cement mixer.

Police have said they are confident the woman who died on Tuesday morning is Sheila Karsberg, 79, from the Highgate area, although she has not yet been formally identified and her next of kin are still being sought.

Ms Karsberg was well loved by many dog-walkers who would see her around Hampstead Heath, Highgate and Camden Town.

She took part in a BBC documentary, Wonderland, in October 2012, in which she spoke of her love her dog, Millie, saying she meant “the whole world” to her.

She was pronounced dead at the scene in Pratt Street close to the junction with Camden High Street shortly after paramedics and police were called at around 9.40am.

Camden Council ran a public consultation on plans to change the layout of Pratt Street and Delancey Street last year after a spate of accidents, but no action has yet been taken to make the area safer. Proposals to improve safety for cyclists and pedestrians are set to be discussed at a council meeting on Monday.

Police said the driver of the vehicle stopped at the scene and no arrests were made.

Officers are keen to speak with the driver of a silver van which passed through the scene moments after the collision who is likely to have witnessed it.

This driver and anyone else who believes they witnessed the collision is asked to call 020 8991 9555.
