COUNTER terrorism officers have raided two homes this morning in connection with the death of exiled Pakistani politician Dr Imran Farooq.
Members of the Metropolitan Police's Counter Terrorism Command executed search warrants at two addresses in north-west London. They have made no arrests.
Dr Farooq was a leading member of the Muttahida Quami Movement Party - his native country's third largest party - and a 50-year-old father-of-two.
He was returning from work in Old Street, east London, and was walking from Edgware Tube station when he was attacked outside his home in Green Lane, Edgware, shortly before 5.30pm on Thursday, September 16, 2010.
A post-mortem examination gave his cause of death as multiple stab wounds and blunt trauma to the head.
On the first anniversary of Dr Farooq's death, the police instigated a £20,000 reward for information which leads to the identification, arrest and prosecution of those responsible.
Detective Chief Superintendent Neil Basu, the then Borough Commander of Barnet, said at that time: "Dr Imran Farooq was killed in a brutal manner outside his own home and his death has left the community with a deep sense of loss."
The Counter Terrorism Command took over the murder investigation in 2011 and carried out a raid on a business address in Edgware in December. 

A Metropolitan Police spokeswoman confirmed no-one has ever been arrested in the case although eight people were interviewed under caution in connection with the ongoing investigation.
