Police say the fatal stabbings of two 16-year-old boys just a mile apart in south-east London are linked.
One boy was found with stab wounds in Titmuss Avenue, Thamesmead, and the other in Sewell Road, on Saturday afternoon.
As neighbours mourned the losses of the boys, police revealed on Sunday afternoon they are keen to hear from anyone who may have seen a dark-coloured SUV-type vehicle in the area.
Detective superintendent Richard McDonagh, speaking at the scene of one of the incidents, told reporters: “Homicide colleagues are investigating and are treating the two murders as linked.
