Police have arrested four men on suspicion of allegedly plotting to carry out a terrorist attack, which security sources say may have been imminent.
The decision to carry out the raids, with one man being held at gunpoint by officers in west London, came after surveillance lasting several months in the capital and the Home Counties.
The suspects, aged 19, 22, 25 and 27, were taken to central London police stations while properties, in London and High Wycombe in Buckinghamshire, as well as cars, were searched.
Detectives are investigating if the group was moving material for a possible attack in the near future. The law agencies refused to discuss details of specific targets, but the arrests took place with Remembrance Sunday approaching and amid warnings of possible attacks on public events.
One of the suspects, say local people in High Wycombe, had his passport revoked earlier in the year. There are said to be no apparent links between the suspects and Isis.Reuse content
