A teacher is claiming he was the victim of racial discrimination, bullying and sexual harassment in the staff room.

The teacher, who was born in Nigeria, is also accusing colleagues and students of calling him abusive names at the school where he worked for four months last year.

The teacher claims he has suffered distress and trauma and has not been able to get another job at a school.

He told a tribunal the discrimination started on his first day when a male colleague winked at him, wiped his hand between his legs and said: "Mmm, those are lovely trousers you've got on."

He claimed he was regularly insulted and abused because of his African background.

A colleague told him: "One thing you guys all have in common is your lovely black ass," the tribunal heard yesterday.

The teacher, who lives near Brighton, read a 28-page statement to the hearing detailing a catalogue of allegations.

These included the day he was reduced to tears by the headteacher who suggested he went back to the jungle and called him "Negro boy".

He complained about a lack of support when police arrested him in connection with an allegation that he had indecently assaulted a teenage boy. After an investigation he was not charged.

He claimed a gay teacher threatened to force him to have sex saying: "I can either pay you or gang rape you."

He claimed a teacher with a cocaine problem punched him.

He had problems dealing with disruptive children and claimed he was threatened with dismissal for giving detentions to students for appalling behaviour, including using racist language in lessons and bringing in weapons, such as knives, baseball bats and a replica air pistol.

He said children refused to be disciplined and threatened him with allegations of assault if he did not leave them to continue their behaviour.

He accused a teacher of using unnecessary force to remove a mobile phone from a female pupil's bra.

He claimed he saw two gay teachers kissing affectionately in a classroom and there were indecent physical activities in the staff toilet.

He said his repeated complaints to the headteacher were ignored and he was convinced he was treated differently to white colleagues.

He accused the headteacher of badgering him into resigning. The man, who resigned last autumn, has bought a claim for race discrimination at an employment tribunal.

If he wins the case, due to last another three days, he wants the tribunal to order the school to give him back his job.

The school, which denies the allegations, successfully applied to the tribunal for reporting restrictions on the case.

The Argus has been banned from identifying the school or the teacher until a decision has been reached.
