POLICE are appealing for witnesses after four youths were stabbed in Uxbridge.

The incident, which involved around ten youngsters, took place on a 427 bus which was travelling along Uxbridge Road, towards Hayes.

Officers were called some time after 12.10am on Wednesday morning after a scuffle involving the gang spilled out on to the street near the Blue Dragon Cleaners.

Four teenagers, two aged 15, one aged 16 and one aged 17, received stab wounds and were taken to hospital.

The 17-year-old remains in hospital but is not thought to be in a life-threatening condition. The others have since been discharged.

Hillingdon Police confirmed that no weapons have been recovered and it is uncertain what was used to stab the four black teenagers.
