Detectives investigating a robbery in Bradford in which a shopkeeper had part of his thumb chopped off have released CCTV images of the gang they suspect were involved.
Shop owner Tasawar Iqbal, 39, was badly wounded injury in an altercation with a group of four men armed with a gun and a machete at his convenience store in Wibsey Park Avenue, Wibsey, shortly after 10.45pm on Wednesday.
He was taken to Bradford Royal Infirmary for emergency surgery.
The suspects, thought to be a group of Asian males in their late teens, were last seen running off towards Farfield Avenue.
Detective Chief Inspector Tony Nicholson, who is leading the investigation, said: "This was a nasty incident, and it has left the victim with an injury which potentially threatens his livelihood.
"This was an innocent man who was trying to stop his premises from being robbed.
"No-one should have to suffer such injuries protecting their property, and that is why I am calling on the local community to come forward with any information they might have.
"Somebody will know who is responsible for this and I would urge them to contact police on 101, or if they would prefer, to give information anonymously to Crimestoppers on 0800 555 111."
