DETECTIVES have released these images of a man they wish to speak to in connection with a string of armed raids around Teddington.
An attempted robbery at Barclays Bank in Hampton Hill High Street last Thursday (July 8) was the sixth in the area in the last year.
Police believe the three robberies and three attempted robberies, in all of which the man involved claimed to have a gun, are all connected.
The first raid, on April 1, at 3.50pm, took place at Barclays in Teddington. The robber waited in line before handing the cashier a note demanding money. He fled with a 'substantial' amount of cash. The man returned to the branch on May 27, at 12.15pm, again passing the cashier a note.
He said he had a gun in a carrier bag and would shoot the employee's colleagues and customers if they refused to hand over the money.
Last Thursday's atempted robbery, at 2.30pm, followed a similar pattern but on this occasion the suspect fled empty-handed.
The same man is also believed to be responsible for a robbery at the Halifax in Teddington on May 20 last year and two attempted robberies on July 17 last year, at the Halifax in Whitton and Santander in Twickenham.
He is believed to be aged between 45 and 55, about 5ft10 and of medium build, with pock-marked skin. He speaks with a London accent and has worn glasses during each of the robberies.
Anyone with information is asked to call the Flying Squad at Barnes on 020 8247 4804 or Crimestoppers, free and anonymously, on 0800 555 111.
