British police have arrested four men in their 30s on suspicion of committing offenses under the Terrorism Act.

Police said the men were arrested Wednesday morning on suspicion of being involved in the commission, preparation and instigation of acts of terrorism.

Police say searches are being conducted at seven separate addresses in Luton, 30 miles (50 kms) north of London, where the men were arrested. Vehicles are also being searched.

Police say the arrests are not related to the recent ISIS group attacks on Paris.
