A man was arrested on suspicion of murder in the English city of Nottingham Tuesday after three people were found dead and three others were hit and injured by a van in related early-morning incidents, police said. “This is an horrific and tragic incident which has claimed the lives of three people,” said Nottinghamshire Police Chief Constable Kate Meynell. She said two people were found dead in one street just after 4 a.m. and a third on a different street. The three wounded by the van were at a different location and were being treated in a hospital. There was no immediate word on their condition. Witness Lynn Haggitt told reporters that a white van pulled up beside her at 5:30 a.m. and she saw the driver look in his mirror and spot a police car approaching slowly from behind without its lights on. The van then drove into a man and woman at a street corner.
