This is the horrifying moment an armed gang burst into a jewellers and beat a terrified shop worker with a hammer during a £250,000 heist.
Dramatic CCTV shows the robbers storming into the store in broad daylight after one of them posed as a customer in order to trick staff into opening the door.
The five masked yobs then rushed into the SP Green in Birmingham's historic Jewellery Quarter and start pocketing items worth thousands from display cabinets.
Gang member Owen Richardson, 21, can be seen violently lashing out with the hammer as he repeatedly attacks a member of staff, who cowers on the floor.
Daijon Johnson and Jamul Pinnock-Parkes, both 20, ransack the store, while the shop worker is repeatedly stamped on by Richardson.
