Flying Squad detectives are appealing for witnesses and information following a series of armed robberies in Camden and Islington.
Images and moving CCTV footage are being released in an attempt to identify three males in connection with the investigation.
Police were called at around 05.40hrs on 1 October to a report of an armed robbery at Tesco in Camden Road NW1.
Two male suspects entered the store, and while one produced a handgun which he pointed towards staff, the second proceeded to steal a number of items.
Just 40 minutes later, the same suspects went into the Nisa Local in York Way, N1 and carried out an identical offence.
At around 03.20hrs on 4 October the same two suspects went into the same Nisa store, this time accompanied by a third male. The group waved a handgun, knife and hammer at members of the public inside the store before stealing goods.
Suspect A is described as Asian, 6ft tall, aged in his 20s, dressed in black, including tracksuit bottoms with grey pockets.
Suspect B is described as Asian, 5 ft 7″ tall, approximately 20-30 years old and also wore all black, including a hoodie with a “MYPROTEIN” logo.
There is no description of the third suspect.
Detective Constable Will Wigzell from the Central Specialist Crime Flying Squad, is leading the investigation and said: “This was a very frightening experience for the victims involved, thankfully none of whom were injured.
“These are very serious offences and we are keen to identify those responsible as soon as possible.
“Officers have carried out a number of inquiries and are now appealing to the public for assistance. Do you have any information that could help us? Do you recognise the males in the images?”
