Police were called at about 1pm on Tuesday, 20 October to reports of a robbery at a shop in Grand Parade, Finchley.
The suspect, who was armed with a knife, got into a struggle with a male and female member of staff and stabbed the male victim. He was taken to hospital with a non life-threatening injury. The female victim sustained a laceration to her hand.
The suspect made off with a number of stolen items – including the victims’ bank cards.
Flying Squad officers attended the scene. While detectives were conducting CCTV enquiries regarding the subsequent use of the stolen bank cards an officer spotted the suspect in Finchley High Road.
The Flying Squad detectives, assisted by local North West Basic Command Unit officers, confronted the suspect who then threatened officers with a large kitchen knife.
A Taser was deployed and the 27-year-old suspect, who was found in possession of the stolen property, was arrested on suspicion of robbery and grievous bodily harm with intent.
He has been taken to a north London police station where he remains in custody.
Detective Sergeant Gary Taylor, from the Flying Squad, said: “This incident is a great example of fantastic teamwork between Flying Squad and local officers, who were quickly able to identify and arrest a dangerous individual. Our thoughts are with the victims and we wish them a speedy recovery.
“Sadly, this incident is also an example of the dangers police officers face day in, day out while protecting the communities they serve. Luckily, no officers were harmed during the confrontation with the suspect as they were able to bring the situation to a safe conclusion.
“Violence towards police officers or members of the public will not be tolerated and we are dedicated to ensuring such offenders are swiftly brought to justice.”
