Thames Valley Police is issuing CCTV images following an armed robbery in Sonning Common.
At approximately 10pm on Sunday (8/4), a man entered the Co-Operative store in Wood Lane armed with a knife and threatened two members of staff.
He told one staff member to take him to the safes and ordered the other to lay on the floor.
