CCTV released by South Wales Police shows how a staff member in a Llandaff store was threatened by a man and forced to hand over cash. Officers want to speak to a man who bought the same type of mask the robber was wearing. Although the masks are widely available, officers wish to eliminate this man from their enquiries. Llandaff councillor Kirsty Davies expressed concern for staff at the store because they are "quite young." She added: "I just really think it's horrendous for staff and maybe they need to get tighter security."
