Continuing their search to find the murderer of former Muttahida Quami Movement (MQM) parliamentarian Dr Imran Farooq, the Scotland Yard anti-terrorism officers on Wednesday conducted more raids.
Earlier, the police had raided two houses in the same area. A British-Pakistani was also interrogated in connection with this case.
The latest search operations represent the first public sign of progress in the case after a hiatus of over a year, although London’s police service insisted the investigation remained “active”. The searches are continuing.
Detectives had previously said that while they were open-minded about the motive, the attack would have required careful planning and Farooq’s killers may have had help.
In September 2011, one year after Farooq’s murder, police had offered a reward of £20,000 for information that could take the case further.
