Warrants have been granted to further detain two men arrested in east London on Monday and three others following a counter terrorism operation carried out by the Met and Kent police forces.

A 24-year-old and a 40-year-old were arrested in pre-dawn raids at two east London addresses on Monday on suspicion of being concerned in commissioning, preparing or instigating acts of terrorism contrary to the 2000 Terrorism Act.

A 28-year-old man was arrested four hours later at Dover port on the Kent Coast.

This followed a swoop late Sunday night by armed police from the Met’s SO15 Command, supported by Kent police, who arrested a 33-year-old when they stopped a vehicle going outbound at Dover port.

Five men are now in custody after the warrants for further detention were granted yesterday.

Addresses were also being searched yesterday in east London and south London as part of the investigation.
