DETECTIVES have released a computer generated image of a man they want to speak to following a vicious attack on a teenager in Fleetwood.
The 18-year-old received a broken jaw during the shocking incident but escaped after a man stepped in and held back his attacker.
Officers have tried to track down the Good Samaritan through media appeals which have so far come to nothing.
Now police have issued the Evofit image as they bid to track down the man responsible for the assault at 3.45am on Sunday, November 18 at Lord Street.
They have also reiterated their appeal for the witness to come forward.
Anybody with any information can contact police on 101 or Crimestoppers on 0800 555111.
