Police in Northern Ireland arrest five men for questioning about the murder of Catholic police officer Ronan Kerr, who was killed by a car bomb in Omagh last April.
The five men were detained in a major security operation involving up to 200 officers.
They were arrested under the Terrorism Act and have been taken for questioning to the serious crime suite at Antrim police station.
Searches were also carried out in Coalisland, Co Tyrone, and Toome, Co Antrim, as well as Bellaghy and Ballyronan, south Derry.
A number of items were seized at the search locations, including clothing, mobile phones, computers and vehicles. They have been removed for forensic examination and analysis.
One man from Omagh has previously been charged in connection with the police investigation into Constable Kerr’s murder.
The officer in charge of the investigation, Detective Superintendent Raymond Murray, said: “Our determination to pursue every possible line of inquiry remains undiminished.
“The investigation is progressing and police have been encouraged by the support and assistance which has been forthcoming from across the community.
“During this search stage, we would ask for people’s continued patience and co-operation as we work to complete our inquiries to maximum effect, as expeditiously as possible and with the minimum amount of disruption to community life.”
Police said a £50,000 reward remains on offer for information leading to the arrest and conviction of those responsible for Constable Kerr’s murder.
