Three people were killed and another three seriously injured when a man went on a stabbing spree in a park in the southern English town of Reading on Saturday, though police said they were not currently treating the incident as terrorism.
Witnesses said a man went on the rampage at around 1800 GMT in Forbury Gardens, stabbing people at random who had gathered in the park on a sunny summer evening in Reading, which is about 40 miles (65 km) west of London.
A 25-year-old man from Reading was arrested on suspicion of murder, police said, adding that they were not searching for any more suspects.
“There is no intelligence to suggest that there is any further danger to the public, however we urge people to remain vigilant and report anything suspicious by calling police,” Detective Chief Superintendent Ian Hunter said.
“This is not currently being treated as a terrorism incident, however officers are keeping an open mind as to the motivation for the incident and are being supported by colleagues from Counter Terrorism Policing South East.”
A witness who spoke to the BBC, Lawrence Wort, said the attack began when a man suddenly veered toward a group of about eight to 10 friends and began stabbing them, “so the first three he got so completely out of the blue, he got very badly”.
Wort said the assailant locked eyes with him and the person he was with and started coming toward them, but they ran to safety, at which point the man turned back to attack another group. When everyone started running from the scene, the attacker ran from the park, Wort said.
“My thoughts are with all of those affected by the appalling incident in Reading and my thanks to the emergency services on the scene,” Prime Minister Boris Johnson said.
Video footage posted on Twitter showed paramedics rushing to help at least three people who were bleeding on the ground. Reuters was unable to verify the footage independently.
