Four men have been arrested on suspicion of planning a UK-linked terror plot.

All four men, aged 18, 24, 25 and 27, were detained in East London and remain in custody at a South London police station.

Three of the men were arrested at their home addresses, but the 24-year-old was taken from near his property in the area.

These arrests were pre-planned as part of an ongoing investigation by the Met's Counter Terrorism Command and MI5

They have all been arrested on suspicion of being concerned in the commission, preparation or instigation of acts of terrorism under section 41 Terrorism Act 2000.

The arrests are linked to activity in the UK.

Officers are currently searching five residential addresses in east London and one business address, also in east London.

The arrests were pre-planned as part of an ongoing investigation by the Met's Counter Terrorism Command and MI5.
