An additional address is now being searched in Stocksbridge, Sheffield in connection with arrests made by counter terrorism police earlier this morning.

This takes the total number of properties to five; four in Sheffield and one in Chesterfield.

The Army's Bomb Disposal Unit is currently attending the address in Chesterfield.

As a precautionary measure and in the interest of public safety, the immediate area has been cordoned off and local residents evacuated while a thorough search is carried out.

Counter terrorism police say they recognise that local people may have concerns as a result of this activity and ask people to remain alert but not alarmed and are grateful for the assistance and understanding of people locally.

The public may have heard loud bangs at the time police entered the properties, reassurances have been made that this was part of the method of entry to gain access.

Residents are being told they will be kept as informed as possible and are being thanked for their understanding, patience and support as enquiries continue.
