CCTV of a "frenzied" chicken shop stabbing has been released in a bid to find the culprits.

A 17-year-old had to be airlifted to hospital after sustaining multiple stab wounds at the Tennessee Chicken Shop in Oval, south London.

He was later discharged.

Detective Inspector Ian Kenward said: "This was a frenzied attack in which a knife was used to inflict life threatening injuries on a teenage male.

"Police will do everything in their powers to bring the offenders to justice. We are appealing for help from the public to assist in identifying those involved."

The attack took place at about 5.30pm on 29 February - but the suspects are also believed to be responsible for another assault at the Brixton Road takeaway earlier that day.

Police want to speak to anyone who saw either incident.

The footage shows two black men thought to be teenagers, wearing black clothing and hooded jackets.

One suspect was about 5ft 11ins, with grey tracksuit bottoms.

Anyone with information is asked to call Crimestoppers anonymously on 0800 555 111 or Lambeth CID on 07785 774 447.
