Detectives investigating the murder of a man who was on the brink of launching a political career have launched an appeal for information on the four-year anniversary of his death.
Dr Imran Farooq was on his way home from work when he was attacked outside his home in Green Lane, Edgware, shortly before 5.30pm on September 16.
Two arrests have been made in connection with the murder, including one made last month following a raid at an address in Waltham Forest.
A police spokesman said: “Detectives from the Met Police Counter Terrorism Command who are investigating his murder are committed to finding those responsible.
“To date they have spoken to 4,466 people, reviewed 7,401 documents and followed up 2,379 lines of inquiry and seized 3,900 exhibits in order to bring his killers to justice.
“This remains an ongoing investigation and we continue to liaise closely with the authorities from Pakistan.
“A number of lines of inquiry are being actively pursued.
“It is thought that his murder would have required careful planning and help from other people, some of whom may have provided assistance or information unwittingly.
“We understand that people may have concerns in speaking to the police and would like to offer reassurance that information will be dealt with sensitively.”
Detectives believe that Dr Farooq was about to launch a new independent political career before his death and this remains a key line of inquiry in this investigation for officers.
Earlier this year police issued a statement outlining their wish to speak with Moshin Ali Syed, 29, and Muhammad Kashif Khan Kamran, 35, who are both believed to currently reside in Pakistan however were in the UK during the time of the murder.
