The security alert at Lake Street in Lurgan has ended and the rail line re-opened.
The alert followed a report that several devices had been left in the area but nothing suspicious was found.
Chief Inspector Jon Burrows said: “ I would like to apologize to all those who have been inconvenienced by the alert here in Lurgan today. The blame for the inconvenience, however, lies squarely with a small group of individuals who have absolutely nothing to offer local people or society in general, and I would like to appeal to anyone who can assist us with our enquiries into this incident to contact police in Lurgan on 101 quoting reference number 1465 01/08/18. 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.”
