A woman was arrested today by detectives investigating the murder of a policeman who was blown up by dissident republicans earlier this year.
The suspect (aged 23) joins five men already being questioned as part of a major security operation involving around 200 officers.
Constable Ronan Kerr, 25, a Catholic member of the Police Service of Northern Ireland, was killed when a booby-trap bomb exploded under his car outside his home in Omagh, Co Tyrone, on April 2.
The five men were detained yesterday. The woman was arrested in Omagh this morning.
Police have confirmed the arrests were connected to the murder and associated incidents.
Searches were also carried out in Coalisland, Co Tyrone, and Toome, Co Antrim, as well as Bellaghy and Ballyronan, south Derry. Today, more searches are being carried out in Omagh.
The suspects were arrested under the Terrorism Act and taken to the Serious Crime Suite at Antrim police station for questioning, a police spokesman confirmed.
A £50,000 (€56,584) reward remains on offer for information leading to the arrest and conviction of those responsible for Constable Kerr’s murder.
