Detectives are re-appealing for information on a man involved in incidents in Lichfield and Burntwood.
The man was captured on CCTV and is believed to be from the West Midlands area.
On December 29, 2012, he entered the Santander bank on Market Street in Lichfield at 11.10am and threatened staff, telling them he had a gun. However, he left empty-handed and no-one was injured in the incident.
At 9.50pm on the same day a man with the same description entered Bargain Booze on Chase Road in Burntwood and threatened workers with a bottle of bleach before stealing money and making off on foot towards Lichfield.
The offender is white, 5ft 7ins to 6ft tall and of medium build with receding hair. He was wearing blue jeans and brown trainers with a black jacket and protruding grey hood. He walked with a distinct limp.
Insp Jed White, Lichfield District Local Policing Team Commander, said: “These types of incidents are very rare in both Lichfield and Burntwood. When they do happen we are committed to bringing offenders to justice and are continuing to try to trace this man.
“We are reappealing for the public, particularly those in the West Midlands area, to help us identify and locate him and I would urge anyone with any information to contact us immediately.”
Anyone with any information is urged to call Staffordshire Police on 101 quoting incident 224 of December 29. Alternatively, they can contact independent charity Crimestoppers, anonymously, on 0800 555 111.
