Two moped robbers who arrogantly called themselves the 'EasyCash Gang' as they targeted 17 phone shops in a terrifying series of smash and grab raids are facing years behind bars.

The robbers stole phones, tablet computers and caused damage worth more than £1 million using hammers, knives, a gun and even a fencing post as a battering ram.

They targeted different Three Mobile outlets several times in the early hours of the morning to grab the latest handsets and were in and out in 'a matter of minutes'.

At Blackfriars Crown Court today Bobby Kennedy, 22, (left) and Chris Costi, 19, (right) were found guilty after trial of conspiracy to commit aggravated burglary at stores across London

At Blackfriars Crown Court today Bobby Kennedy, 22, and Chris Costi, 19, were found guilty after trial of conspiracy to commit aggravated burglary at stores across London.

Kennedy, wearing a black t-shirt, remained emotionless while Costi, in a buttoned up white shirt, briefly acknowledged family members in the public gallery as they were led from the dock following the jury's unanimous verdict.

Three other members of the gang Alfie Kennedy, 20, brother of Bobby, Dylan Castano-Lopez, 19, and Adam Atallah, 21, all previously pleaded guilty to their part in the conspiracy.

Kennedy, who is a known member of The EC, or 'EasyCash Gang' as is his younger brother, had only been released from prison two weeks before joining the raiders.

CCTV footage captured the moment gang members entered a Three Mobile shop in East Ham in September last year

He had been in prison until September last year after being convicted of similar offences involving mopeds and the use of knives.

Members of the gang threatened to shoot security guards if they got in their way.

In one raid at the Three store in Oxford Street, central London, at 2.40am one of the raiders also threatened a member of the public with a gun.

Another raid at a Wood Green store left two officers with cuts after a violent struggle with some of the gang.

Four men allegedly used a battering ram to smash their way into the north London store armed with hammers and knives.

Police found them inside the shop and discharged tasers but they had no effect, as they could not penetrate the gang's purposefully worn extra thick clothing.

CCTV footage from the first burglary in Walthamstow at 5am on 1 May, last year, showed four burglars using two mopeds in a carefully planned raid.

Each of the gang knew their specific role and were well drilled in what to do.

Two of the gang were seen smashing though the front window, wearing black clothes and crash helmets.

Footage from inside the stock room shows the door smashed off its hinges before making their escape on the mopeds.

The whole raid took just over three minutes.

CCTV footage from inside another store showed a security guard, who had tried to hide, being attacked and beaten by the gang, who hit him with a chair.

Jurors viewed dramatic footage from a police helicopter of a ten-mile high-speed chase of four of the gang on two mopeds through the streets of London after the last of the burglaries in late October.

The gang targeted some shops more than once, with the Walthamstow branch of Three being hit four times.

Three placed security guards in stores overnight, but they were brutally attacked by gang members with chairs and hammers, while others swiped phones and tablets from the storeroom.

Adam Atallah, 21, also admitted his role in the conspiracy

All the raids followed a similar pattern as after getting away on the waiting mopeds the gang would dump them and book a cab away from the area.

Within hours they would often link back up at the Shuttleworth Hostel in Hackney and then meet with two shop owners in east London.

Those shop owners would buy the latest model phones from them, before selling them on to countries around the world.

Some were found as far away as in Bangladesh and Pakistan.

It is estimated the total value of the stolen phones and tablets and the damage caused to the shops was £1million in just over six months.

Police officers built up a picture of the raider's movements through messages and pictures from mobile phones and cell site evidence that placed them in the area of the stores at the same time as the burglaries.

Three placed trackers in dummy phones that were taken by the gang, which revealed their movements after they were stolen.

The gang followed a pattern of lying low for a few hours, sometimes taking the stolen phones and tablets to the Shuttleworth Hostel, before selling them on.

Pictures taken from the gang's phones included images of members kitted out in their specialist gear of thick dark clothing, gloves and helmets just before a raid.

Kennedy admitted involvement in one raid after being caught by police at the scene but denied he knew weapons were involved or taking part in any other burglaries.

Police officers said he could be identified at least one other burglary by a pair of distinctive trainers.

He did not give evidence during the trial.

Kennedy is closely connected to other members of the gang and clothing he was wearing when arrested with his brother and Atallah matched clothing seen in CCTV footage from stores.

Two hammers were found in his possession when he was arrested after a raid on 14 October, he had only been released from prison on licence on 30 September.

Between 2013 and 2015 Kennedy was involved in similar group offending involving mopeds and the use of knives.

Costi, who has no previous convictions, claimed to have been going to McDonald's when his phone was tracked driving through the area at the time of the Wood Green raid.

He gave evidence saying he drove to the fast food restaurant between 12am-5am and admitted meeting up with other gang members but denied any knowledge of the crime.

One officer identified Costi, who is a close friend of Atallah, as being at one of the raids.

Kennedy, of no fixed address and Costi, of Hackney, east London, denied one count of conspiracy to commit aggravated burglary.

But the jury of eight men and four women took three and a half hours to unanimously find them guilty.

Judge Michael Simon remanded them both in custody.

They will be sentenced with Alfie Kennedy, Castano-Lopez and Atallah following a further trial involving other alleged gang members in October.
