Farroukh is one of two suspects related to the attack. Images of the suspect were published by the British media after he was arrested in Hounslow, West of London, on Saturday night. The attack was caused by an improvised explosive device, which contained a timer but failed to fully detonate. The Islamic State claimed responsibility for what was the fifth attack in the country over the past six months.
