A 17-year-old boy is fighting for life after a late night attack on a quiet road in south London.
Emergency services raced to the scene of a "disturbance" in Shrublands Avenue, Croydon – near Shirley Youth and Community Centre – shortly after 11.30pm on Friday.
Paramedics rushed the boy, who had suffered head injuries, to a hospital in south London.
His condition is critical, Scotland Yard said.
A Met Police spokesman added that there have been no arrests.
A police cordon was put in place for several hours and motorists are warned to avoid the area.
