The investigation into the disappearance of Mohammed Shah Subhani from Hounslow, is now being treated as murder.
Detective Chief Inspector Noel McHugh from Specialist Crime, said:
"Unfortunately today I am having to appeal for the public’s help in the murder of Mohammed ‘Shah’ Subhani.
"The fact no-one has heard from Shah, since he went missing three months ago, and ballistic evidence recovered from his car, has convinced me he is, sadly, no longer alive.
"This news has been devastating for his family and we are doing all we can to support them."
Police were called on Tuesday, 7th May 2019 after 27-year-old Shah failed to return to his home in Hounslow, West London.
His family reported him as missing shortly before midnight, having seen him last at 12:30hrs that same day.
An extensive police inquiry was launched to find Mohammed and there have been numerous appeals for the public’s help.
Shah’s white Audi Q3 [genuine VRM LC67 CXS], was recovered on false plates, L88 EJF, in Camden on Wednesday, 19 June 2019.
At around 18:30hrs, officers were informed that the occupants of a white Audi had been involved in an argument with another group of people on Robert Street, NW1.
The occupants were alleged to have been in possession of weapons.
Officers located the car and an authorised pursuit took place. The Audi collided with a second vehicle before being abandoned; the three occupants fled on foot.
The car was subject to a full forensic investigation.
DCI McHugh added:
"The investigation is active and well-resourced and four people have been arrested in the course of the inquiry.
"Searches have been conducted in the area that Shah went missing and in fact, for two days, every available search asset in the Met was dedicated to searching for him.
"We are also offering a substantial reward of £20,000 for information that leads us to find Shah or the arrest of those involved in his disappearance.
"Our priority is to locate Shah and bring those responsible for taking him to justice.
"Part of the appeal today relates to the whereabouts of Shah’s car after he went missing.
"We want to see anyone who may have seen this car or had any interaction with it. We will look sympathetically on anyone who comes forward with information about how this came to be on false plates.
"Significantly, the car contained scans of Shah’s baby at 16 and 20 weeks.
"The baby is due on 31 August, just a few weeks away. Think of the pain you could ease by letting his family know what happened on the day he went missing.
"Only a small group of people would have known what Shah’s movements were that day, and we strongly believe that those in the know are those who were close to him.
"Lastly, let me say that no family should have to suffer the fears and uncertainty that Shah’s family are enduring.
"Anyone with information, no matter how small, should contact police on 101, quoting Operation Rockton.
