Officers have released video of a man who robbed a petrol station three times on two separate nights.
The man covered his face with his hand in the first incident and wore a mask similar to one from the film Saw in the other two incidents at the Marmion Service Station, Carlton Road, Thorneywood.
He escaped with cash from the till after threatening the shop worker in the first incident – seen here on CCTV – at about 12.50am on Sunday (23 April 2017). He also stole chocolate and energy drinks on his way out.
He was wearing a Saw mask when he returned at 4.20am the same day and again threatened staff and took cash, as well as cigarettes.
The man was described as black, about 5ft 8ins, of average build, wearing a three-quarter length black jacket, black gloves with white stripes on them and black and grey Nike Air Jordan trainers. He was also carrying a black, blue and red rucksack.
Anyone with information about the incidents or the identity of the man is urged to call Nottinghamshire Police on 101, quoting incident numbers 36 and 136 of the 23 April and 41 of 25 April 2017 respectively. Alternatively, call Crimestoppers anonymously on 0800 555 111.
