A teacher convicted of multiple counts of indecent assault continued to work at a Hertfordshire school despite police warnings and concerns from local safeguarding officials, according to documents and testimony revealed following her recent conviction.

Sally-Anne Bowen, 65, was found guilty last month of seven counts of indecent assault involving two boys she taught during the 1980s. One victim, referred to as “Gareth” to protect his identity, was 14 when Bowen engaged in sexual activity with him at her home, in view of several teachers from Christ’s College Finchley (CCF), where she worked at the time. Despite warnings from police that Bowen was under investigation for allegations of sexual abuse at a different school in Hertfordshire, she was allowed to continue teaching.

Records show that Bowen taught at 15 different schools after the incidents at CCF. In 2014, Gareth reported Bowen to police when she was teaching chemistry at Astley Cooper, a mixed secondary school in Hemel Hempstead, Hertfordshire. She was then 53 years old. Following the police report, local safeguarding officials, including Tony Purvis, the designated officer responsible for managing child protection cases, said the allegations met the threshold for suspension. However, Bowen remained in the classroom with restrictions: lessons had to be conducted with a laboratory technician present and the classroom door open.

Meeting notes from that period describe a “plan hatched” by Purvis and Astley Cooper’s headteacher, Edward Gaynor, to allow Bowen to continue teaching despite serious allegations. She remained employed at the school until August 2021. Gaynor later testified at the Teaching Regulation Agency (TRA) hearing that he believed Bowen’s denials even though he had not seen the evidence against her.

After the Crown Prosecution Service (CPS) initially opted not to pursue charges in 2018, Gareth referred his concerns to the TRA. In 2024, the agency issued Bowen a lifetime teaching ban. Local authorities have said that current safeguarding standards would make it highly unusual for a professional to remain working after allegations of this nature.

Bowen’s conviction also sparked criticism of how CCF handled earlier reports of abuse. Evidence presented at trial indicated that staff at the school in the 1980s were aware of concerns but failed to take appropriate action or notify subsequent employers. Former staff, including headteacher Brian Fletcher and Bowen’s supervisor Richard Luker, gave conflicting accounts in police interviews and court, with Fletcher denying concerns despite evidence suggesting he was informed of the allegations.

Matthew Stevens, now headmaster at Saracens High School in Barnet and Bowen’s superior at Astley Cooper, testified at the TRA hearing dismissing Gareth’s claims and questioning the victim’s character. Stevens told investigators that his testimony did not reflect his professional judgement on sexual misconduct.

Christ’s College Finchley issued a statement expressing sympathy for the victims but noted the abuse occurred under previous governance. Hertfordshire County Council indicated discrepancies between safeguarding records and the notes shared during the TRA hearing, underscoring the need for clearer record-keeping and stronger safeguarding measures going forward.

Gareth expressed disappointment not only with the institutional failures to prevent Bowen’s continued employment but also with staff members who, in his view, attempted to discredit survivors. The case has raised questions about safeguarding practices in schools and the responsibilities of educational institutions when facing allegations of historic abuse.
