Police have released mobile phone footage of two men emerging from a branch of Nationwide they had just tried to rob.
The footage was recorded by an onlooker as the two men fled the building and got into a car.
The two men, who were wearing motorcycle helmets, pulled a knife on staff at the Nationwide in Leicester Road, Wigston at 11.15am on Wednesday last week.
They left empty-handed in a dark silver grey Ford MPV-type vehicle. Nobody was injured.
Detective Constable Eliot Burgess, of Leicestershire Police, said: "We hope by releasing the footage someone may remember seeing something of significance.
"Did you see two people acting suspiciously around the premises or do you recognise the vehicle?
"The vehicle was displaying false registration plates which may have since been changed again.
"If you can help with any aspect of the investigation then please contact us.
"Also if you were in the Leicester Road area of Wigston during the morning of 11 May and haven't yet spoken to the police, get in touch."
Contact Det Con Burgess on 101, quoting crime number 115681.
