Police given more time to question terror four
Anti-terror police have been given five more days to question four men suspected of plotting to attack the UK.
Magistrates have given officers until next Tuesday to question the men, all aged 20 or 21, who were arrested under the Terrorism Act.
They were detained in raids in London throughout the day on Tuesday which saw one of them Tasered.
Whitehall officials have said the police operation "may have foiled the early stages" of a planned UK attack.
The BBC understands one of the arrested men is medical student Tarik Hassane, from west London.
Under terror legislation the men could in theory be held without charge and questioned for up to 14 days.
They were detained on suspicion of being involved in the commission, preparation or instigation of terrorism.
A number of homes and vehicles were searched by specialist officers in west and central London on Tuesday as part of the investigation.
Mr Hassane, thought to be the 21-year-old who was Tasered during the joint operation by MI5 and the Met, was not injured and did not require medical treatment, police said.
