This is the shocking moment a notorious moped thug brandished a foot-long hunting knife during a raid at a designer store in Islington.

Shahruk Sheraji, 22, who is already serving a two-year sentence for his part in a string of mobile phone snatches in the capital, was jailed for a further nine years at Blackfriars crown court.

He pleaded guilty on Monday at the same court to a moped-enabled knifepoint commercial robbery at the store in Upper Street in November last year, Scotland Yard said.

Police released CCTV footage of the terrifying incident on Wednesday in a bid to catch seven other suspects who were involved.

In the clip, Sheraji is shown heading towards the shop counter waving the huge blade menacingly. The shop assistant holds up their hands and cowers in fear, while four other suspects are seen grabbing designer gear and fleeing.​

Sheraji and another thief were jailed last year after CCTV footage showed them driving the wrong way down a motorway during a 90mph police chase after they snatched 18 mobile phones from pedestrians in one afternoon in London.

During the Upper Street incident that began at 5.15pm on November 16, 2016, four mopeds - all with pillion passengers - mounted the kerb outside the shop on Upper Street, police said.

Three riders kept watch over the mopeds outside of the shop while one rider and four passengers ran into the store, officers added.

As Sheraji headed for the counter, dropping a black knife sheath in the doorway, four suspects grabbed more than £20,000 worth of designer jackets by Armani, Canada Goose, Hugo Boss and Moncler.

They then made off on mopeds, which had registration plates removed.

A member of staff called police and officers obtained the CCTV footage which showed Sheraji dropping the black knife sheaf.

Sheraji's DNA was found on the sheath, according to police.

When he was arrested on November 26, he was found with more than a dozen phones and jackets matching those seen in the CCTV.

Detective Constable Steffan Evans, of the Camden and Islington CID, said: "Moped-enabled offences are a high priority for Camden and Islington and this investigation shows that moped-enabled thefts and knife crime are taken seriously.

"This planned attack at the shop left those who witnessed it feeling terrorised. The public should feel reassured that we are working to make the streets of London safer."

Detective Chief Inspector Christine Jessah, from the Central North Command Unit, said: "As a result of the painstaking detective work by officers in Central North CID, a dangerous offender is off the streets and this lengthy sentence should be a deterrent to others."

Police would like to hear from anyone with any information which could help find the seven other suspects involved in the robbery.
