Farooq, 50, a founding member of the Muttahida Qaumi Movement (MQM), was on his way home from work in north London when he was attacked. Police believe he had been under surveillance in the days and weeks before his murder.
Detectives from the Metropolitan Police's Counter Terrorism Command said they had arrested a 30-year-old man at a house in east London on suspicion of being involved in Farooq's murder. He has been taken to a central London police station for questioning.
The arrest is the second made by London police in the hunt for Farooq's killer. In June last year a 52-year-old man was arrested at Heathrow Airport on suspicion of conspiracy to murder after landing on a flight from Canada.
He remains on police bail while detectives continue their investigation and is due to return to a London police station in late October.
Farooq claimed asylum in Britain in 1999 after more than seven years on the run from Pakistani police who accused him of involvement in murder and other serious crimes, charges he denied.
He had been inactive in politics for about two years before he was murdered outside his home in Edgware. Police said they found a 5-1/2 inch kitchen knife and a brick used in the attack at the scene.
Farooq was one of several senior members of the MQM who had sought refuge in London. The party's top leader Altaf Hussain, who is wanted in Pakistan in relation to a murder case, has also lived in self-imposed exile in the British capital since 1992.
He himself was arrested, in June this year, on suspicion of money-laundering, leading to protests which led to lockdown in Karachi as shopkeepers and market-stall owners closed their businesses.Güncelleme Tarihi: 27 Ağustos 2014, 15:50
