A viable incendiary device has been found in the grounds of Ballycastle police station.
Army bomb disposal experts were called to the Co Antrim PSNI station after the discovery of two suspicious objects.
Homes and businesses on Ramoan Road in the seaside town were evacuated and a controlled explosion was carried out during the alert.
PSNI Inspector Tony Boyce said: “A controlled explosion was carried out following the discovery of two devices.
“The first device was a viable incendiary device and the second a hoax device.
“People have returned to business premises in the area and the Ramoan Road can be accessed as usual.”
Alliance Policing Board member, Trevor Lunn MLA, condemned those behind the two devices that were discovered.
He said: “They just wish to bring violence and disruption onto our streets and have no care for who may be injured or killed by their actions.
“The vast majority of the public are opposed to the actions of these thugs.
“Those behind these devices are a danger to the public and must be urgently apprehended by the police.”
Sinn Fein MLA for North Antrim Daithi McKay posted on Twitter: “No one in their right mind wants to see bombs placed in Ballycastle.
“No support for this here, glad that staff and locals can get back to their day.”
