Second arrest in N.Ireland police murder case
Police were questioning a second man on Thursday in the investigation into the murder of a Catholic policeman in Northern Ireland, police said.
The 40-year-old suspect was arrested after police stopped a car on the road between Omagh, where the policeman was killed on Saturday, and the town of Ballygawley.
He is being questioned with a 26-year-old man, who was arrested when police swooped on a van in a residential street in Scotland on Wednesday.
Both men are also being questioned about an arms dump found in Northern Ireland, which included Kalashnikov rifles, ammunitions and explosives, possibly Semtex.
Police described the find as "one of the most significant in recent years".
Constable Ronan Kerr was killed when an under-car booby trap bomb exploded as he left home for work.
No group has yet claimed responsibility but the murder has been blamed on dissident republicans opposed to the peace process in the British-run province and is believed to be aimed at deterring Catholics from joining the police.
The policeman's funeral on Wednesday produced a remarkable show of cross-community condemnation of the first murder of a policeman in Northern Ireland for two years.
