A man has been arrested on suspicion of murder after three people were killed in Nottingham city centre, with a further three left injured.
Nottinghamshire police said people had been left dead in the street after one incident, while in another a van had tried to run over others. Police said a 31-year-old had been arrested on suspicion of murder, and they believed all three incidents were linked.
An eyewitness has told how he witnessed a young man and young woman being stabbed on Ilkeston Road, close to the junction with Bright Street, at about 04:00.
The three attacks have not been declared as a terrorist incident, with police urgently investigating the background of the man they have in custody as they try to determine a motive.
Police are trying to locate any phone or computers the suspect used, and examining their contents, in order to understand what happened.
The incidents have led to a massive police response, with cordons erected around Nottingham city centre and closures on the city’s tram network.
