Flowers were this morning laid on the Hampstead Heath bench where much-loved Sheila Karsberg used to sit with her dog.

Dog walkers have been paying tribute to Sheila, 79, who was tragically killed after being hit by a cement mixer in Camden High Street.

They have been calling for a memorial bench to be dedicated to Sheila on the Heath.

Today Maria Jakubiec, who works at the Parliament Hill Cafe where Sheila was a regular customer, said: “She was here twice a day with her dog and we will really miss her. She was part of the cafe. We used to take tea out to her as she sat on the bench.

“She always paid and she always had money. She also used to love ice cream, cream teas and get milk for her dog.

“We would love to see a bench dedicated to her.”

Sheila starred in a BBC documentary Wonderland: Walking with Dogs filmed on the Heath two years ago in which she spoke of her love for Milly saying she meant “the whole world” to her.

Sheila’s next of kin are still being sought by police to make a formal identification.

Following the collision, 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 on Tuesday.

Eyewitnesses say she had collapsed or passed out as she crossed the road before being run over.

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.
