A jewellery store employee is in a life-threatening condition after a robbery at a shop in Peterborough. Cambridgeshire Police said six men raided Lala Jewellers on Gladstone Street at about 11:50 GMT on Saturday. A senior councillor later said it was believed the victim was stabbed. Police said shelves were emptied and two employees behind the counter were assaulted before the thieves fled in separate vehicles. Two of the robbers were wearing white, traditional Pakistani clothing, officers added. The injured employee, a 50-year-old man, was taken to hospital, where he remains in a life-threatening condition. Police said they are carrying out a substantial investigation and have appealed for people in Gladstone Street who may have seen something suspicious to come forward. Officers have also agreed to carry out extra patrols in the area over the coming days. The investigation is ongoing.
