The security alert in the Moss Road/Fergleen Road area in Derry/Londonderry has ended.
ATO examined a suspicious object in the area and have declared it to be an elaborate hoax.
Chief Superintendent Gordon McCalmont said: “I want to thank the local community for their patience and understanding during the course of this evening’s policing operation. Thankfully, minimum disruption was caused.
“The blame for any inconvenience caused, however, lies squarely with those individuals who left this in the vicinity of St. Paul’s Primary School, which was being used as a polling station. They have absolutely nothing to offer local people or society in general.
“I want to appeal to anyone who can assist us with our enquiries into this incident to contact police at Strand Road on 101, quoting reference number 1187 of 02/05/19.”
Alternatively, information can also be provided to the independent charity Crimestoppers on 0800 555 111 which is 100% anonymous and gives people the power to speak up and stop crime.
