Five men have been arrested by detectives investigating the attempted murder of police in a bomb blast in Lurgan.
Dissident republicans opposed to the peace process were blamed for last weekend’s attack in the Victoria Street area.
Police said the five suspects, aged 28, 31 and 36, and two 46-year-olds, were detained in Co Armagh over the last 24 hours.
Officers were called to the scene near a cross-border railway line after a phone call to the Samaritans last Saturday claiming a device aimed at a police patrol during the early hours had failed to explode.
Homes were evacuated and a hoax device, which was not capable of detonating, was discovered.
But during a follow-up search by police to declare the area safe a suspected anti-personnel bomb exploded.
No-one was injured in the explosion.
