A knife wielding armed robber bragged about his plans to steal cash from a supermarket just minutes before he was picked up by police.
Andrew Hennells posted “Doing. Tesco. Over” on Facebook at 7.25pm on 13 February, 15 minutes before Norfolk Police were called by a member of the public who witnessed a man demanding money at a branch in King’s Lynn.
The 31-year-old – who was armed with a knife – was found in a nearby pub after walking away with £410 in cash.
He pleaded guilty to robbery and carrying a knife as an offensive weapon when he appeared at Norwich Crown Court.
Sgt Pete Jessop, from King’s Lynn CID, said the Facebook post helped investigators build the case against Hennells.
“It was a bizarre and unusual case,” he said. “The pictures and posts on Facebook helped us confirm what we already knew.
“None of this takes away from the seriousness of the crime or the trauma experienced by the victims of the robbery.”
Hennells is due to be sentenced on 8 April.
