The post-mortem of late MQM Leader Imran Farooq took place at the Finchley Mortuary on Friday.
The report gave the cause of death to be multiple stab wounds and blunt trauma to the head.
Detectives have issued an urgent appeal for witnesses to come forward as they continue their door to door inquiries. A spokesman said the police want to speak to anyone who was in the area at the time or saw the attack.
Counter-terrorism police to investigate murder
The Scotland Yard counter-terrorism police have been called in to lead the murder inquiry into the London killing of MQM Leader Imran Farooq.
Security sources told the Daily Telegraph that the murder inquiry is now being handled by the Counter-Terrorism Command which investigates political assassinations. MI5 is also likely to be called in to help with the hunt for the killers.
At the moment however, counter terrorism officials in Pakistan say it is difficult to put the blame on anyone in particular.
Detectives in London have not ruled out the possibility that Doctor Farooq was killed in a random mugging incident.
Murder not to lower spirits: Altaf
In a telephonic address to the MQM coordination committee in Karachi, Altaf Hussain said that incidents like the killing of Imran Farooq cannot lower the spirit of party workers. Altaf said that he knew Imran Farooq for more than 32 years.
Terming the murder a great tragedy for the party, the MQM chief hoped the killers would be arrested soon.
The MQM has called the murder of one of its highest-ranking members as a deliberate bid to target the party or even send a message.
The leadership of the MQM is in a state of shock and is choosing to stay away from the speculations and rumours that have begun sprouting due to the lack of any semblance of answers. It has therefore said that it is relying on the Scotland Yard to conduct thorough investigations into the murder, adding that it is for this reason that it is not looking to say anything on the matter.
