One of the men accused of killing Ramniklal Jogiya has said a co-defendant entered the victim's shop with a gun hidden beneath a burka.
Charlie Mcauley 20, told Leicester Crown Court his role was to drop someone off at Mr Jogiya's shop but "things got muddled up".
Mr Mcauley said it had first been discussed with his co-accused Thomas Jervis, 24, of Whetstone, and he was "asked to be involved".
He told the judge his understanding of his part was to drive to Mr Jogiya's shop on Belgrave Road, drop someone off and drive away on the night of 24 January.
However, the court heard that Mr Jogiya was taken into the van and Mr Mcauley then drove to a football stadium in Birstall.
He told the jury, while he was driving: "I heard the words 'robbery and alarm' and then I turned the radio up."
Mr Mcauley said Mr Jervis was handed a gun by two individuals in the back of the van and was told to use it when he went back into the shop, dressed in a burka, to scare anyone off if they came in. He held the gun while Mr Jervis put on the burka and saw him put it inside, the court heard. Mr Mcauley denied knowing a gun was part of the plan.
Mr Mcauley, Mr Jervis and Callan Reeve, 20, from Leicester, admit kidnap and robbery but deny murder and manslaughter.
Jacob Roach, 30, denies all the charges.
The trial continues.
