The prosecution argued that he used sick notes to cope with his impossible schedule. In March 2023, he was on sick leave from four of the organisations he worked for. But he kept working at the Home Office and did not tell them he was ill.
His line manager at the UK Health Security Agency (UKHSA), Aleesha Adams, organised a video call with him in May 2023. By this point he’d been off sick for three months and she wanted to make a plan to get him back to work.
She told the jury that at the start of the call he was coughing a lot and waving tissues up to the camera. She also told the jury that he had been wearing white make-up to try to look ill.
Adams told the court that as the meeting went on the make-up started coming off his forehead. ”He was sweating, it was like rubbing off so it was darker underneath and darker on the neck.”
Chowdhury told the jury this was a smear and that he had not been wearing make-up.
After the call, Adams discovered that he had logged into the call using a Defra email address. When she challenged him about it he blamed a technical error.
Adams grew suspicious. ”I believed he was lying,” she told the jury. She escalated her concerns up the chain at the UKHSA.
But his fraudulent behaviour went on for several more months until he left the civil service in September 2023.
He was finally caught in 2024 by the government’s National Fraud Initiative, which conducts searches of civil service databases such as payroll every two years to look for anomalies.
Chowdhury has also been accused by his siblings of bullying their mother into increasing his share of the family home days before she died.
In a case at the High Court, Chowdhury’s two brothers and sister allege that he put “undue influence” on Faijun Nessa to sign documents that meant he would inherit half of her home.
The four-storey, six-bedroom home in east London has been valued at £2.1m.
His siblings say their mother could not have understood what she was signing because she was “desperately unwell”. In January 2023 she was given a terminal diagnosis of stage four metastatic colorectal cancer.
The claimants also allege that Mrs Nessa, who was nearly blind and could not speak English, was unaware of what she was signing because the documents were not translated into her native Bengali at the time they were signed.
Kashim Chowdhury denies the claims. That case is ongoing.
