A women arrested after the discovery of three incendiary devices in County Antrim has been released without charge, police have said.
Four men and another woman who were also arrested after the seizure in Ballymena are still being questioned.
The devices were made safe by Army bomb experts after they were found at Fisherwick Gardens on Saturday. Police described the devices as viable.
At the weekend, the police said the find was significant.
Displaying the devices, Superintendent Terry Shevlin urged the public to be vigilant.
"These are three viable incendiary devices that did not make their target and have saved who knows what damage or injury."
Police said they remained concerned about the wider dissident republican threat in Ballymena.
However, they would only say that the find could be attributable to dissident republican activity.
A wave of fire bombings has destroyed several businesses across Northern Ireland in recent months.
