A cocky burglar, who walked out of an east London cafe with the till, returned soon after, claiming he was from head office when challenged.
Detectives from Tower Hamlets have issued this CCTV footage of a man they wish to identify and speak to in connection with the incident.
On Friday, September 9, last year police were called at around 8.15pm to reports of a burglary at Nido Tower, Frying Pan Alley, Stepney.
CCTV captured the moment a suspect walked into the cafe and began to look around.
He then removed the cash till and walked off.
He later returned and when challenged, said he was from head office, and continued to look around the cafe.
He was then told to leave.
The suspect is described as a slim black man, 5ft 8ins tall with short black hair, a black beard and wearing a black and white camouflage vest and dark trousers.
He was described as having a glazed expression by those who saw him.
Detective Constable Sol Hamid, who leads the investigation for Tower Hamlets CID, said: "We are keen to hear from anyone can identify the man shown in the footage or the image released, or anyone who witnessed the incident."
Anyone that can assist the investigation is asked to contact Tower Hamlets CID via 101.
