A social worker died of multiple injuries when she grabbed hold of a garage's roller shutter door which pulled her upwards and crushed her, an inquest heard.

Heidi Chalkley, 40, was heading for a night out in Cambridge with Susan Gilmore when she asked her friend if she had ever held onto the garage doors when the mechanism pulled the shutters up.

Ms Gilmore said, "No," and seconds later she watched her friend die in the entrance to the car park of her block of flats as Ms Chalkley was lifted three feet off the ground.

In a statement read by Cambridgeshire's assistant coroner Sean Horstead, Ms Gilmore said: "We had planned to go out for a drink in Cambridge. Before going out I planned to drop my car off at home."

She drove in to the car park as normal, using a clicker to open the door, with the barrier - a metal grille - rising into a box at the top.

Ms Gilmore said she parked and both women walked towards the barrier which goes out on to the street.

"As we planned on going straight out and into town, we walked towards the barrier rather than to the internal doors and going into the flat," she said.
