A 48-year-old man has been arrested in Wrexham on suspicion of terrorism offences.
Police said the man, whom they did not identify, was held on Thursday on suspicion of being concerned in the commission, preparation and instigation of acts of terrorism, under section 41 of the Terrorism Act 2000.
He was arrested as part of a joint operation between the Welsh extremism counter-terrorism unit, North Wales police and the West Midlands counter-terrorism unit.
A police spokesman said: “The man is being questioned at a police station in the West Midlands. The arrest was preplanned and intelligence-led. There was no threat to the public’s safety. An address in Wrexham is the subject of an ongoing search.”
Officers have 48 hours to question the suspect before charging or releasing him or applying for a warrant of further detention.
