Alliance Councillor Gerardine Mulvenna has condemned those behind a serious incident in the Linn Road area of Larne last night.
A barricade was set on fire across the street, with unconfirmed reports of masked men in the area - reports Gerardine has described as "disturbing".
She added: "I've been in touch with the PSNI today to establish what exactly took place and what is being done to tackle this blatant attack on the rule of law.
"The scenes which unfolded last night are extremely concerning, recalling images linked to the darkest days of our past, showcasing an attempt to place fear and intimidation at the heart of our community.
"This cannot be allowed to happen and as a community we must stand together against these attempts to drive us backwards. I would urge anyone with information to contact the PSNI as soon as possible, ensuring those behind this attack on our future are never allowed to strike again."
