Four people have been arrested in Radcliffe in connection with firearms offences.
Armed officers carried out a warrant just after 2pm today in Shelford Road as part of a planned operation.
Two men and a woman were taken into custody on suspicion of possession of a firearm without certificate. Another woman was arrested for breach of peace. They remain in police custody.
Nottinghamshire Police said it wanted to reassure local residents that there was no ongoing threat to them and that officers would remain in the area for the next day or so.
