Police are this morning continuing to question a 14-year-old boy who was arrested yesterday on suspicion of attempted murder after a teacher was stabbed in front of pupils.

The teenager, who cannot be named for legal reasons, was arrested in Bradford city centre yesterday afternoon following a six-hour manhunt.

Earlier in the day, a teacher at Dixons Kings Academy, named locally as Vincent Uzomah, was stabbed in the stomach as he prepared to teach a science lesson.

The teenager fled the Lidget Green school, but police announced an arrest at 4pm yesterday.

The 14-year-old is now being questioned by detectives for a second day over the stabbing, which apparently followed a dispute over a mobile phone.

The teacher, who had been working at the school for a few weeks, was taken to hospital and was last night said to be in a stable, non-life threatening condition with his family by his bedside.

His relatives have said they will not be speaking to the media and have requested that their privacy is respected at this difficult time. 

The youngster fled the scene straight after the attack, scaling a perimeter fence.

Video footage purporting to show the boy being arrested has been posted online by a number of people and shared tens of thousands of times - in some versions the boy's face can be clearly seen.

A number of police officers are seen to handcuff s suspect and lead him away as members of the public look on.

A spokesman for West Yorkshire Police said: "Police would also like to ask the public and the media to refrain from speculating about the arrested person's identity, as any attempt to identify this person via social media or otherwise may prejudice court proceedings."

Meanwhile, it has emerged that Mr Uzomah is on the books of a casting agency.

A spokesman for the Seven Casting agency said Mr Uzomah had worked on soaps including Emmerdale and Coronation Street.

He said: "Vincent is a very nice, reliable, bubbly guy. He's genuine and easy to get on with.

"He's worked on a few of the northern soaps and has done things in Emmerdale and Coronation Street.

"He's always very reliable and courteous."

The spokesman said staff at the agency were shocked when they heard about the stabbing.

"It was a shock when we first heard about it in the news and then to find out it was Vincent was even more shocking. It's absolutely crazy but thankfully it sounds like he is going to be okay," he said.
