POLICE are trying to trace a good samaritan who intervened in an assault in which a 17-year-old suffered three fractures to his jaw.
The incident happened after the teenager left the Cube Shisha Lounge, in Darwen Street, Blackburn, at around 7.30pm on Thursday (Jan 3).
He was approached by two men, and a fight broke out outside the Tasty Spot takeaway, also in Darwen Street.
The assault continued until the group reached the Youth Zone, in Jubilee Street, where a driver stopped her car and disturbed the offenders, police said.
The victim was was in hospital and was due to have an operation for his injuries yesterday (Fri).
A 19-year-old man from Blackburn has been arrested on suspicion of section 18 grievous bodily harm with intent.
Police are now looking to trace the woman, who was driving a dark coloured seven-seater Vauxhall vehicle.
DI Mark Vaughton, from Blackburn police, said she could have very important information that would help them trace the second man.
He said: “This appears to be a nasty assault involving an innocent member of the public, who has been enjoying an evening out in Blackburn town centre.
“One man has been arrested and we are actively seeking another in connection with the offence.
“I am thankful to the member of the public who intervened and assisted the victim and we are keen to speak to her to get a full account of what she may have seen.”
Anybody with any information about the attack is asked to call police on 101 or Crimestoppers anonymously on 0800 555111.
