A teacher who head-butted a teenage boy and told him to "shut the f*** up" in a shocking attack has been told he can no longer work in the teaching profession.
Craig Embrey, 31, of Warrington, was sacked after leaving a 16-year-old who goes to a special school needing three stitches.
A row broke out when Embrey encountered two teenagers who were on their way back from a house party in his street on January 18 last year, according to the Liverpool Echo.
Prosecutor Louise Santamera told Liverpool Crown Court that the victim and his friend had left the house party after seeing the size of the crowd there.
Ms Santamera said: “They were singing as they left but suddenly found themselves confronted by the defendant who appeared to be angry.
“He told them to ‘Shut the f*** up’.”
The court heard that the boys told him to "cool it" and said they were leaving.

But instead of letting the matter rest, Embrey head-butted one of them.
Police, who Embrey had called, arrived on the scene, and Embrey gave his name but then ran away. When he reached home his partner contacted the police and he was questioned.
Embrey claims he was out looking for a relative of his partner as he was alarmed by the large group near his house.
He met the boys who were “singing and swearing at the top of their voices and he told them to shut up”, the court heard.
He told them there were children sleeping and that they had caused his dogs to start barking.
Embrey claimed the boy he assaulted had threatened do "do him in" and that one of them had "approached him at speed one with his arms raised as if to strike him".
Embrey said he panicked and reacted by head-butting him.

But he denied intending to injure him and expressed remorse, said Ms Santamera.
A judge said that he accepted that the 31-year-old thought he was about to be attacked and “had genuinely but mistakenly misjudged the situation”.
Judge Gary Woodhall said: “You were not about to be attacked. They were in no way to blame. As you approached you told the boys to ‘F*** off’ and committed the assault.
“The level of force used was on any view excessive. You continued to deny intending to cause any harm.
“I conclude that is unrealistic. If you head-butt someone in the face [you] must have intended some harm.”
He added: “A probation officer says it was a highly compulsive offence and an isolated incident, which I accept.”
Michael Davies, defending, said that Embrey, who has no previous convictions, had lost his job as a result of the incident and told even if acquitted he could no longer work in the teaching profession.
Embrey pleaded guilty to assault causing actual bodily harm.
He was ordered to pay his victim £900 compensation and the judge also imposed a community order for nine months.
The defendant, whose heavily pregnant partner was in the public gallery, was also ordered to carry out 10 days rehabilitation activities and 90 hours unpaid work.
The judge ordered Embrey, who now works in the pharmaceutical industry, to pay £300 prosecution costs and told him that they and the compensation must be paid at £100 a month.
