Terror suspects were arrested in Hounslow, Uxbridge and Southall last night as police swooped to stop a suspected Islamist terror plot.

Three men arrested at those addresses and a fourth arrested in High Wycombe remain in custody this afternoon, as the investigation continues.

Counter terror police are this afternoon still searching addresses in Hounslow, Uxbridge, Southall, Greenford, Hayes and High Wycombe.

A 22-year-old man was arrested in Hounslow last night at 8.45pm, 14 minutes after a 27-year-old man had been arrested in a car in a Southall street.

Firearms officers assisted with both those arrests and a third in High Wycombe, also at 8.45pm last night, in which a 19-year-old man was arrested. No shots were fired in any of the operations.

A 25-year-old was arrested at a property in Uxbridge at 2.55am this morning but firearms officers were not involved that time.

All four men were arrested on suspicion of being concerned in the commission, preparation of instigation of acts of terrorism.

A Hounslow woman last month appeared in court accused of aiding terrorist plans in Syria. She was bailed to return to the Old Bailey in January
