The former Head of Science was caught out after a pupil recorded their conversation in which he offered to have sex with her when she turned 18
A South London teacher has been banned from the classroom for life after a disciplinary panel heard he made sexually explicit and flirtatious remarks to a teenage pupil. The comments by Amrinder Singh Pannu including saying “you’re one horny girl” and discussing having sex with her after she turned 18.
Mr Pannu, 38, formerly Head of Science at St Mark’s Church of England Academy in Mitcham, was recorded making a series of inappropriate comments to the pupil, referred to as Pupil A, during a private conversation. The remarks included use of the phrase “a nice arse” and asking: “So you could do me round the corner?”
In a decision published on September 26, 2025, the Teaching Regulation Agency (TRA) found that the comments were not only sexual in nature but sexually motivated, constituting serious misconduct and a breach of professional standards. The panel ruled that Mr Pannu, who had worked at the school since September 2015, had failed to uphold basic safeguarding responsibilities and had brought the teaching profession into disrepute.
The recordings of Mr Pannu was made by Pupil A in a classroom during a free period. Pupil A described her relationship with Mr Pannu as mutually flirtatious and said she recorded their conversations after a friend, who doubted her account of the situation, asked her to provide proof.
Mr Pannu was also recorded saying “just have it, just have it init, just the way you have your t**s” in reference to his penis. He also said “if you were in a different school then it would have been a different story” and agreed to have sexual intercourse with Pupil A “a few month in” after she turned 18.
In September 2018 three members of staff at the school received an anonymous whistleblowing email containing three voice recordings of a conversation between Mr Pannu and Pupil A. The email alleged that the exchange was sexually explicit and, following this, Mr Pannu was suspended while the school launched a formal investigation.
He admitted to some of the comments, including agreeing to have sex with the pupil once she reached 18, but claimed they were not sexually motivated. The panel disagreed, describing his behaviour as “a pattern of flirtatious and inappropriate conversation”.
In its written decision, the TRA panel said: “Mr Pannu’s comments went far beyond any acceptable boundaries between teacher and pupil. His actions were not accidental or isolated, they were deliberate and deeply inappropriate.”
Mr Pannu apologised for the comments and said he recognised how badly he handled the situation. He said he had spent many hours and days since the incident replaying the moments.
However, the panel stated: “Mr Pannu demonstrated the beginnings of remorse but not meaningful remorse.”
While Mr Pannu insisted he didn’t want to blame the pupil, he also claimed she had deliberately targeted him, alleging she was the one who started the sexual conversations in an attempt to fabricate a relationship.
The panel recommended a prohibition order with no opportunity for review, a decision that was upheld by the Secretary of State for Education. This means Mr Pannu is permanently banned from teaching in England.
He does, however, have the right to appeal the order to the High Court within 28 days of receiving formal notice. St Mark’s Academy did not want to comment on the incident.
A spokesperson for Anthem Schools Trust, which runs St Mark’s, said: “The teacher in question was suspended and dismissed seven years ago as soon as this incident came to light. This is a case from 2018 which occurred under historic leadership and no current student at the school was taught by the individual concerned.
“St Mark’s is committed to the wellbeing and success of all its students and this is why the school has been rated by Ofsted as ‘Outstanding’ in all areas, following its recent inspection in 2024.”
