Ronan Kerr murder - five arrested in search operation 26 July 2011 Last updated at 07:44 GMT

 

Five men have been arrested and a major search operation is underway across Northern Ireland over the murder of police officer Ronan Kerr.

The 25-year-old Catholic policeman was killed when a bomb exploded under his car in Omagh on 2 April.
About 200 officers are currently involved in seven searches in Coalisland, Toome, Bellaghy and Ballyronan.
The five men, aged from 22 to 46, were arrested under the Terrorism Act.
Before Tuesday's operation, a total of 33 searches had been conducted in connection with the murder in Northern Ireland, the Republic of Ireland and Scotland.
The police investigation is being led by detectives from the Serious Crime Branch.
All five men have been taken to Antrim police station for questioning.
Police said clothing, mobile phones, computers and cars had all been seized for forensic analysis.

Detective Superintendent Raymond Murray said: "Our determination to pursue every possible line of enquiry remains undiminished.

"The investigation is progressing and police have been encouraged by the support and assistance which has been forthcoming from across the community."
He appealed for patience and cooperation as the police operation continued.
Constable Kerr, who joined the police in May 2010, is the second officer to have been killed since the Royal Ulster Constabulary became the PSNI in 2001.
Dissident republicans were blamed for the murder.
