A bloody ambush saw an 18-year-old man stabbed to death and a boy left with serious injuries as they were set upon while travelling through Leeds in a taxi.
West Yorkshire Police have launched a murder investigation in the wake of the violence which involved three people from another vehicle attacking the two teenagers.
One of the taxi passengers, named locally as Jamie Meah, was rushed to hospital but was pronounced dead a short time later. A murder investigation has now been launched.
