A 74-year-old woman was punched in the stomach and back before her mobile phone was stolen in a sickening attack as she shopped in Morrisons in Heckmondwike.
The incident happened on Saturday morning between 10am and noon.
The pensioner was carrying a black canvas bag and pushing a trolley when she was approached by two Asian teenagers around aisle 13 of the Union Street store.
One suspect punched t
he victim in the stomach and the other punched her in the back before they unzipped the canvas bag and stole a mobile phone from it. They then fled.
The 74-year old was left very shaken by the incident but otherwise unharmed.
Both suspects are believed to be in their late teens. One had long curly hair, tied in a pony tail, was around 5ft 5in, slim and wearing a red vest top and blue jeans. She may have had a nose ring and head jewellery which went across her head in a half moon shape.
The second was about 5ft 3in, slim, with black long hair tied in a pony tail. She was wearing a blue and white striped T-shirt, blue jeans and a thick gold rope chain.
It is possible that the two suspects may have followed the victim around the store before attacking her.
