An 18-year-old man who pistol-whipped a Catford shopkeeper in an armed robbery has been jailed.

Nazim 'Naz' McClarren, of Hither Green Lane, was sentenced to four years imprisonment at Woolwich Crown Court on February 2.

The teenager pleaded guilty to robbery and possession of an imitation firearm at the same court on December 2 last year.

Police were called to the convenience store in Brookdale Road shortly before 8pm on April 6 last year to reports of an armed robbery.

McClarren threatened the shopkeeper - a man in his 30s - with a what he believed to be a gun and demanded money from the till.

He then put the shopkeeper in a head-lock, hitting him repeatedly over the head with what was later found to be an imitation firearm.

McClarren took cash from the till and then ran off.

Forensic officers carried out tests on the imitation firearm as well as on the till and they found fingerprints and DNA belonging to McClarren.

He was arrested on July 22 and charged the following day with robbery and possession of an imitation firearm.
