A convicted killer held up a store with a hammer because he believed the owner had stashed away a lot of money.

But all Robert Baker got was £108 – and a 10-year extended jail sentence.

Baker, from Walmer Castle Road, Walmer, had gone to MJ Stores in Victoria Road, Deal, in November.

Prosecutor Simon Taylor said the 38-year-old asked manager Mohammed Harrou if he could use the toilet.

Canterbury Crown Court heard how he was refused and left the shop but returned three minutes later and chose a beer.

He went to the counter as if to pay but grabbed Mr Harrou’s scarf and dragged him through the store shouting: “Shut up, shut up... don’t talk!”

The terrified manager was dragged upstairs into a kitchen and Baker grabbed money from a till after producing the hammer.

Mr Taylor said Baker continued to shout: “Where is the other money?” and began dragging the manager downstairs.

Mr Harrou broke free and ran into the street shouting: “Help!” and then told a neighbour: “It’s a robbery!”

His neighbour and two others ran after Baker and detained him until police officers arrived.

The court heard Baker, who has committed previous robberies, carried out the attack while he was under an indefinite licence after being convicted in 2003 for manslaughter.

Judge Simon Taylor ruled that he posed a danger to the public and jailed him for five years and four months, with another four years and eight months to be served on licence when he is released.
