The two Rotherham men, aged 34 and 37, also arrested on Sunday, remain in police custody and officers will continue to search one of the men's addresses.


On Sunday anti-terror police swooped on addresses in Aston and Swallownest and made three arrests.

A 20-year-old woman from Rotherham was one of three people arrested on Sunday morning after specialists from the Counter Terrorism Unit in Leeds were alerted after police investigating a burglary in Aston, near Sheffield, found "suspicious material" inside the property.

Last night South Yorkshire Police confirmed she has now been released without charge over the terrorism offences but bailed for drugs and burglary offences pending further enquiries.





A search of the Aston house suggested links to a property on Alexander Road, Swallownest, also near Sheffield, and when officers raided the home in the early hours of Monday they also discovered more items of concern.

The nature of the material has not yet been disclosed but an army bomb disposal unit was called to the Swallownest address on Wednesday.

Materials likely to cause concern and trigger arrests under the Terrorism Act include explosives but also items connected to certain political or ideological causes or anything which suggests an intent to cause harm.

Police chiefs say investigations between the Counter Terrorism Unit and the South Yorkshire force are ongoing at this time.
