Counter-terrorism police are investigating an incident that has left two women seriously injured in Leeds.
A crossbow and firearm were found at the scene, on Otley Road in the Headingley area, shortly after 2.47pm on Saturday.
Counter Terrorism Policing North East said it had taken over the investigation “due to the circumstances surrounding the incident”.
The third person injured, a 38-year-old man, has been arrested and taken to the hospital due to a self-inflicted injury.
A statement from Counter Terrorism Policing North East said: “Due to the circumstances surrounding the incident, Counter Terrorism Policing North East have taken responsibility for leading the investigation with the support of West Yorkshire police.
“Extensive enquiries continue to establish the full circumstances and explore any potential motivation.”
The head of CTP North East, DCI James Dunkerley, said: “From the enquiries undertaken so far, there is no evidence to suggest anyone else was involved in the attack, and, at this time, we are not looking for anyone else in relation to the incident.”
Assistant chief constable Carl Galvin of West Yorkshire police, who commanded the police operation, said: “We have an extensive number of uniformed officers deployed in the Otley Road area this evening to reassure residents and continue our enquiries at the crime scenes.
“I also want to thank members of the public for the support they gave victims and the emergency services as we attended the scene.
“We would strongly urge people not to speculate online or share information or footage which could affect the active investigation and continue to work closely with colleagues from Counter Terrorism Policing North East.”
The incident followed a threat that was made on social media targeting the Otley area.
Bethany Connelly, who works in the area, told Yorkshire Live: “I was at work at a nearby restaurant and some girls were sitting outside.
“They asked if they could come in and finish what they were having because they’d seen someone with a crossbow. This was all before the incident, and a few minutes later, we saw ambulances and police rushing down the roads.
“The roads were getting blocked off, and we’d been told by police to keep everyone indoors and away from the area.”
Part of Otley Road has been closed off by police.
Rachel Reeves, the chancellor and MP for Leeds West and Pudsey, said the incident was shocking, telling the BBC: “My thoughts are with all of those affected.”
