Police have launched an appeal for information after a 24-year-old man was stabbed in the stomach, back and neck after refusing to hand over his phone to two men in Kilburn on Friday.

The “vicious” assault- which left the victim requiring extensive surgery- took place at around 11:35 pm in Kilburn High Road after the victim made his way by bus from Lisson Grove in Marylebone.

As the victim walked outside number 230 Kilburn High road, two men-described as being black and in their twenties- approached the victim and blocked his path in both directions.

The man standing in front of him demanded: “Give me your phone or you will get stabbed.”

After the victim did not hand his phone over, the suspect standing behind him stabbed him in the stomach, back and neck.

Detective Constable Lee Gordon said: “This was a vicious assault on a busy road so I am confident that someone must have witnessed the incident. I urge anyone with information to contact me urgently so I can try to take these dangerous men off our streets.”

Camden Police have asked witnesses or anyone with information to call CID on 101 quoting reference CRIS 6513246/15 or contact Crimestoppers on 0800 555 111.
