Detectives name man wanted in connection with Hanwell murder

Homicide detectives investigating a murder which took place nearly a year ago have named a man they want to speak to as part of their investigation.

A Crimestoppers reward of £10,000 has been announced for anyone who comes forward with vital information that leads to the arrest and prosecution of Siavosh Mohammad-Khani.

Police were called at around 22:15hrs on Monday, 10 February 2025, to a pub in Oaklands Road, Hanwell, to reports that a man had stumbled into the premises with serious injuries.

Officers attended the scene alongside London Ambulance Service crews, and found 33-year-old Dariusz Serafin there with knife wounds. Despite the efforts of paramedics, he was pronounced dead at the scene.

Over the past year, homicide detectives have conducted extensive enquiries to find those responsible for Dariusz's death. They now want to speak to Siavosh Mohammad-Khani, 34, in connection with the murder.

Officers have released an image of Mohammad-Khani, together with footage of him taken on the day of the murder. The video shows him at a garage in Marylebone with a vehicle - a black BMW X4 car, with the registration HV67 RZP - that is believed to have been used by Dariusz’s killers on the night of the murder

Detective Chief Inspector Alison Foxwell, who is leading the Met's investigation, said:

"Dariusz's death was a tragedy and we are working tirelessly to get justice for his family. Since last year we have worked to piece together vital clues of what took place that night and are now asking for the public’s help as part of our enquiries.

“We are appealing directly to anyone with information to please do the right thing and come forward – even the smallest detail might prove vital. My team and I know how daunting giving information can be, but I would urge anyone who knows where Mohammad-Khani is to get in touch with police or Crimestoppers. We also want to hear from anyone who saw or might have CCTV or dash cam footage of what we believe was the killers' car, a black BMW X4.”

Anyone who can help is asked to call police on 101, quoting CAD 7176/10FEB25 or visit the Major Incident Police Portal.

Alternatively people can report through independent charity Crimestoppers on 0800 555 111 or via its website. Any information given to Crimestoppers will be completely anonymised before it is passed onto police and will remain so.

Crimestoppers is offering the reward for any information which leads to the arrest and conviction of Siavosh Mohammad-Khani. The reward is available for three months and is due to expire on 5 May 2026.

Alexa Loukas, Greater London, Regional Manager at the charity Crimestoppers, said:

“If you have any information about where Siavosh Mohammad-Khani is, please speak up and tell our charity what you know. Crimestoppers exists to give a safe and secure way for anyone who is unwilling to speak directly to the police. We are independent and, crucially, guarantee everyone stays completely anonymous.

“We are not interested in who you are and will never ask for any your personal details; we just want to know where Siavosh Mohammad-Khani is. Tell us what you know, and we’ll pass your information on. Dariusz’s family are desperate for answers and need justice. You could make a huge difference in this tragic case.

“With our guarantee of anonymity, you will never have to speak to the police, attend a court or provide a witness statement.”
