A general practitioner from Taunted has been permanently removed from the medical register. Nicholas Chapman, 57, was convicted of making a female colleague unwittingly ingest his semen by placing it in her coffee.

The shocking revelation emerged after the colleague, known only as Ms B, noticed her drinks tasted “salty” and left a “thick gloopy” residue in the sink. It later became clear that Chapman had been using specimen pots—filled with semen—to taint beverages he offered her.


Timeline of Abuse

Chapman’s disturbing actions spanned several years and were uncovered following a police investigation in 2021. According to court records, Ms B collected a sample of coffee he made and turned it over to authorities. Tests confirmed the presence of the defendant’s DNA.

He was subsequently found guilty at Gloucester Crown Court in 2023 for engaging in sexual activity without consent on September 13, 2021. 

Chapman claimed he suffered from a condition that caused involuntary discharge of semen while defecating and insisted someone must have placed the specimen in her coffee as a “prank.” Yet no evidence supporting his condition existed on his medical records.


Tribunal Findings

Between June 23 and July 8, 2025, the Medical Practitioners Tribunal Service (MPTS) reviewed Chapman’s conduct and found multiple instances of sexual harassment against another colleague, Ms A. This included showing images of “unclothed women and/or that were pornographic in nature” and photographs of an “erect penis.”

The tribunal accepted that Chapman had also asked Ms A why she hadn’t found him on a dating app and suggested she should “look for [him]” there. In 2020, he kissed her on the lips and, in May 2021, hugged and touched her bottom—actions that were all “found proved.”

Chairman Jonathan Storey said: “Erasure would send a message to the medical profession and to the public that this type of behaviour was unacceptable.”

The panel emphasized that it received “no evidence of apology, reflection, insight or remediation from Dr Chapman in respect of his conviction.”


Victim Testimony

In a moving victim impact statement, Ms B said: 

“I feel betrayed by him, by his actions. He has made me feel powerless. The devious and cowardly nature has shocked me. If this was a physical attack I may have at least had a chance to defend myself. I’ve had to be open about this to my partner and family, but I often feel alone and that no one quite understands. I hope in the future I am able to put this all behind me and move on with my life. Though I have to accept that the mental and emotional trauma I have suffered throughout this will always remain with me in some way.”

She described the first suspicions in 2020, noting: 

“I did not know what it was. I did not suspect it could have been semen at that point. He was then bringing me more drinks – probably one to three cups of coffee a week. At least six times I’ve seen it – I’ve not drunk it since that first time.”

Upon finding specimen pots in his possession, Ms B reported: 

“I instantly suspected he had been putting semen in them and transporting them into my drink. I felt very jumpy and worried he would catch me with this cup. I put the cup into a bag and dropped the sample off (to the police).”

She also described Chapman’s behaviour as “letchy,” and recalled being shown images of his “erect penis” twice. 

“I thought (the first time) it was a mistake and he must be really embarrassed. The second time I felt like it was on purpose. It made me feel very uncomfortable. At times I refused a coffee but he would do it anyway.”


Sentencing and Aftermath

His Honour Judge Rupert Lowe handed Chapman a 12-month community order with 200 hours of unpaid work, and noted: 

“Your defence at trial was absurd and unnecessary. Your claims were implausible and contradictory. You told the police a ridiculous story of having semen on your hand and admitted to masturbating at work. The truth is, you masturbated at work as you had a high sex drive. The impact on your career and personal life has been considerable. You have brought that on yourself.”

In addition to the community service, Chapman received a 10-year restraining order, a five-year notification order, and was ordered to pay £3,500 in court costs.

Analysis of the coffee Ms B submitted from September 13, 2021 confirmed the presence of semen, which matched Chapman’s DNA.

Chapman was trained as a doctor in South Africa, graduating from the University of Cape Town in 1993. His medical career now ends in disgrace.
