Two shootings in London in the space of an hour have left a 17-year-old girl dead and a boy, 16, critically ill. The teenage girl was found with a bullet wound in Tottenham on Monday night and pronounced dead at the scene. The boy had been found with gunshot wounds in Walthamstow earlier, with another boy, 15 who had stab injuries. Stella Creasy, MP for Walthamstow, said the 16-year-old boy – who was shot on Markhouse Road and taken to a hospital in east London – is still in “intensive care”. She added that the 15-year-old boy’s stab injuries are not thought to be life-threatening. In Tottenham, a police cordon remains in place in Chalgrove Road, near Northumberland Park, where the girl was pronounced dead at 22:43 BST. A witness said a woman, believed to be the victim’s mother, began “screaming” when she discovered the girl shortly after the shooting. David Lammy, MP for Tottenham, said he is “deeply worried” about London’s rise in violent crime – particularly in his area. “There is no single cause, but there has been a big spike in both gun crime and knife crime across London,” he said. “Certainly my constituency finds itself at the epicentre of that. There are real issues about a lack of resources.” A local resident, who did not want to be named, said she heard multiple shots, which sounded like a “bomb” exploding. She said: “It’s not nice. I’ve lived here for 40 years, and in the last two or three years it’s become not a nice place. “There are so many drugs, stabbings and killings.” A neighbour, who did not want to be named, told BBC Radio London that stabbings were common in the area.
