Two men have been charged with armed robberies in which shop staff were threatened with guns.

The men are accused of robbing a Camden Tesco and an Islington Nisa store at gunpoint, before threatening members of the public in a second attack on the Nisa with a third man.

Police were called at around 5.40am on Sunday, October 1 to a report of an armed robbery at Tesco in Camden Road, Camden.

Two male suspects allegedly entered the store. One produced a handgun and pointed it at staff while the second stole a number of items, the Metropolitan Police said.

Just 40 minutes later, the same suspects went into a Nisa Local just a third of a mile away in York Way, in Islington, and allegedly carried out an identical offence.

At around 3.20am on Wednesday, October 4 the same two suspects went into the same Nisa store, this time accompanied by a third man.

The group waved a handgun, knife and hammer at members of the public inside the shop before stealing goods, police said.

Two men were later arrested, charged and have been remanded in custody following a court hearing.

A third male is still on the loose and police are still appealling for any information about his identity.

Det Con Will Wigzell from the Met's Central Specialist Crime Flying Squad said: “This was a very frightening experience for the victims involved, thankfully none of whom were injured.

“We have made good progress since our initial appeal but are keen for any information that helps us identify the third person involved.

"While we don’t have a description for him, I am sure someone out there knows who he is.
