A 14-year-old schoolboy who stabbed a supply teacher in a row over a mobile phone later boasted on Facebook, 'Motherf***** gettin funny so I stick the blade straight in his tummy.'

The teenager, who cannot be named, was arrested after 50-year-old Vincent Uzomah was stabbed in the stomach at Dixons Kings Academy in Bradford on June 11.

He appeared at Bradford Youth Court today where he denied attempted murder but admitted causing grievous bodily harm with intent.

The court heard how the 'dangerous and unpredictable' youngster confessed to police 'I'm really sorry for stabbing my teacher, I don't know what's wrong with me' after the attack during a science lesson.

The boy, who has previous convictions for attempted robbery and battery and was on bail for burglary at the time of the stabbing, sat in the dock flanked by two security guards today.

Wearing blue jeans, a grey shirt and a black puffa-style jacket, he said 'yes, sir' when he confirmed his name and spent much of the rest of the 11-minute hearing with his head bowed.

His plea was accepted by the Crown Prosecution Service and Judge Jonathan Durham Hall QC said the boy will be sentenced at a later date.

Mr Uzomah, a married father-of-two, was taken to hospital after being stabbed in a row over a mobile phone, which the pupil was asked to hand over.

During the confrontation, the 50-year-old Nigerian teacher was stabbed once in the stomach with a kitchen knife.

Described by police as Asian with short dark hair, the schoolboy fled the school in his uniform shortly after the incident, which occurred at about 9am.

Teachers later appealed for the teenager to hand himself in and he was arrested by police in the city centre following a six hour search - a move caught on video by bystanders.

It later emerged the teenager had been at the school for around a year and that there had been previous problems with his behaviour.

Pupils in the Year 10 science class who witnessed the attack claimed it was the result of a row over a mobile phone.

One 13-year-old girl said she saw Mr Uzomah 'hunched' over in a corridor with blood pouring from his stomach.

'We were in the classroom next door and it was really hectic and then we heard that a teacher had been stabbed by a student,' she said.

Another said: 'I heard the boy stabbed the teacher because he took his phone off him. I was disgusted.'

The case was not opened today but Judge Durham Hall said: 'This is a very troubling case.'

He said the teenage boy was 'undoubtedly a very troubled young man' and said Mr Uzomah was 'a very brave and compassionate victim'.

He said he agreed with the CPS decision not to proceed with a charge of attempted murder, saying it would be very difficult to prove the defendant had an intention to kill.

As the boy left the dock the judge thanked him.

He said: 'Your plea has been noted, very proper, at a very early stage. Thank you.'

He said a psychiatric report and a pre-sentence report needed to be prepared before sentencing could take place.

The boy was watched by two members of his family from the public gallery as he was led away. Mr Uzomah was not in court.

At an earlier hearing at Bradford Youth Court on June 13, magistrates heard how the incident took place during a BTEC science lesson.

Prosecutor Anzal Hussain said: 'The defendant had a mobile phone on him, which went off. The teacher asked him to hand it over.

'The defendant walked towards the door and the teacher assumed he was going to pass the phone over to him.

'But the defendant stabbed the teacher and then ran from school.'

After the stabbing the teenager bragged on Facebook: 'Motherf***** gettin funny so I stick the blade straight in his tummy'.

During police interviews he remained silent, but provided a prepared statement, part of which read: 'I'm really sorry for stabbing my teacher, I don't know what's wrong with me.'

Following the incident, Mr Uzomah was taken to hospital but released a few days later following surgery.

He later issued a statement thanking people for their support.

He said: 'I wish to express my heartfelt gratitude to God and to everyone for all the support that myself and family have received during the course of the traumatic event of my life.

'It has been 12 days since this event occurred and I thank the Lord Jesus for sparing my life.'

Mr Uzomah, who has worked as an extra on the soaps Emmerdale and Coronation Street, thanked the doctors and nurses who helped him and the staff at the Dixons Kings Academy.

He said: 'My family and I appreciate the overwhelming support, love and care that we have received from friends and well-wishers, as I continue on the path towards recovery. Thank-you all.'

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

Neighbours of the supply teacher, who lives with his wife Uduak Imeh-Uzomah and their children Samuel, 12, and Glory, 11, in a £150,000 semi-detached house in Leeds, also described him as being friendly and a 'lovely guy'.

There was a heavy police presence at the school in the wake of the attack which occurred at 9am on June 11

The teacher, who suffered non-life threatening injuries, works across Bradford as a supply teacher to fund his own higher education, spending his spare time working towards a PhD at the University of Salford.

His next-door neighbour described him as a 'lovely' guy who is an asset to the community.

'We have spoken about how naughty the children were,' he added.

A woman who lives on the same street said: 'I often see him and his wife and children and they are all very friendly.'

Police arrested the teenager six hours after he fled the school after releasing an appeal for his whereabouts.

Video footage emerged of the arrest and showed the youngster being led away after being told he was being arrested on suspicion of attempted murder. He was also found in possession of cannabis when he was arrested.

The teenager was remanded in custody today and will now be sentenced for the lesser charge of grievous bodily harm with intent at a later date, probably in August.

The attack on Mr Uzomah caused shock in Bradford and took place only 15 miles from Corpus Christi Catholic College in Leeds, where veteran Spanish teacher Ann Maguire was stabbed to death in April last year.
