Police have today asked for help to find the teenagers responsible for an attempted robbery in Keighley.
Officers say the group targeted an 11-year-old boy, who was cycling on the canal path near Swine Lane, Riddlesden, between 4pm and 5pm on Tuesday March 4.
The boy was approached by six youths who demanded that he hand over money.
The youths fled, leaving the boy unhurt, when they were disturbed by a man who is believed to have been in a black VW Golf.
Detective inspector Alan Flynn, of Bradford CID, said: "We are particularly keen to trace this person, as they could have vital information which will assist in our investigation."
Five of the youths were described as white and one as Asian. They were believed to be aged around 13 to 14 years and were of average height and build.
One had short, curly blonde hair, while the others had short fair hair. The Asian male had short black hair which was swept to the side.
All were wearing hooded tops and black trousers. Anyone with information is asked to contact DC Asif Khan at Bradford CID on 101, or Crimestoppers on 0800 555111.
