Nottingham killings: UK's counter-terror police join ‘serious incident’ investigation

British police investigating a “serious incident” in the central England city of Nottingham, where a man was arrested on suspicion of murder on Tuesday after three people were found dead, have said they are keeping an “open mind” over the motive and working alongside counter-terrorism police.

Nottinghamshire Police said they do not believe there is anyone else involved in the incident, which also left three people injured and hospitalised – one of whom is in critical condition.

The chief of the force said they are at the early stages of the investigation and need to determine the motives behind the “horrific and tragic” series of events before releasing further information.

“We are keeping an open mind as we investigate the circumstances surrounding these incidents and are working alongside Counter Terrorism Policing to establish the facts – as we would normally do in these types of circumstances,” said Chief Constable Kate Meynell.

“We do have a man in custody who has been arrested on suspicion of murder. Currently, we do not believe there is anyone else involved in this incident," Meynell said.

"It is safe to go into the city centre, but there are a number of streets that will remain closed, including Ilkeston Road, Magdala Street, Milton Street and Maple Street. This is so officers can gather evidence in order to understand what has happened,” she added.

Earlier, British Prime Minister Rishi Sunak said he is monitoring developments as a 31-year-old man was arrested as a series of attacks unfolded on Tuesday.

Two people were found dead on one street in Nottingham city centre, around 200km north of London, and the third victim was found dead on another street of the city in the early hours of Tuesday. In the third incident, a white van attempted to run over three people on a different street nearby, and those three victims remain in a hospital after suffering injuries.
