A BOMB squad was called in and six people were arrested yesterday morning in anti-terror raids.

Four men from Derby, one from Burton upon Trent and a woman from London were held on suspicion of engaging in the preparation of an act of terrorism. They remain in police custody.

Six properties in Derby, Burton and London were searched in an investigation led by the north-east of England’s counterterrorism unit (Nectu).

An army bomb disposal team was called to the Normanton area of Derby in what police described as a precautionary measure. Forensic teams were seen entering a property in Leopold Street and the road closed.

In a statement, Nectu said: “All six arrests this morning were carried out under terrorism legislation, meaning officers have an initial 48 hours to charge, release or apply for a warrant of further detention.

“The arrests are linked to international-related terrorism.”
