The 26-year-old was arrested in Loughborough and was taken in for questioning about the raid on a convenience store in Sileby. A knife was found in the car in which he was travelling when officers stopped him. A second suspect, also aged 26, has previously been question after he was detained last month. He is currently on bail.
Two masked men carried out the raid at Sileby Minimarket, in Greedon Rise, Sileby on Friday, March 13.
Detective Constable Helen Small said: “Despite the arrests we are still keen to speak to anyone who may have any information about the incident, did you witness it or have you heard rumours locally about it?”
CCTV footage released by the store at the time showed one thug jumping on to the counter to confront the assistant, who put his hands out to defend himself.
In the footage the thug is shown pushing the man backwards, before kicking him in the face three times. The raider then pulled out a hammer and ordered the man to open the till, from which he took £400 to £500.
Store owner Krish Karuna said at the time: “It was shocking how violent this man was. He came over the counter and pushed the shop assistant back. Then he kicked him in the face a few times and was saying, ‘open the till, open the till’. He pulled out a hammer and was swinging it in front of my staff member. These men are dangerous and need to be caught.”
