One of four British men arrested over an alleged terror plot has been released, Scotland Yard has said.
The men were arrested in a series of raids in London on 13 October on suspicion of the commission, preparation or instigation of acts of terrorism.
The 29-year-old was released earlier and has not been charged with any offence.
The other three suspects remain in police custody, a force spokesman said.
Two men, both aged 25, were arrested in a car in Mansell Street, Whitechapel, east London, after police fired “Hatton rounds” – ammunition designed to burst tyres and blow open doors.
One was a British national of Turkish origin and the second was a British national of Algerian origin, police said.
A 28-year-old British national of Azerbaijani origin was arrested outside the premises of Planet Organic in Westbourne Grove, Bayswater, west London.
The 29-year-old who was been released, a British national of Pakistani origin, was arrested in Peckham Hill Street, Peckham, south-east London.
The men were taken to a south London police station.
Whitehall officials said the alleged jihadist plot was “serious” and included plans to use firearms in the UK.
But they said it did not appear to be on anything like the scale of earlier major plots, such as the airline liquid bomb plot or the Birmingham rucksack bomb plot, which resulted in convictions.
