Last Wednesday evening (October 5), at approximately 5.10pm, a man armed with a gun had entered the Post Office in the south Armagh village and threatened staff.
He then made off empty handed and is believed to have left the area in a black coloured Mercedes.
That same vehicle is believed to have been involved in an armed robbery at a service station on the Castleblayney Road in Keady last night (Tuesday).
Police say they are investigating a potential link between the two as well as a further incident on Tuesday night.
Police explained: “Shortly before 7.30pm last night, two men wearing balaclavas and armed with a handgun and wheelbrace entered the store on Castleblayney Road. They threatened a teenage girl who was working there and demanded money. The pair then made off from the scene with a sum of cash in a dark coloured Mercedes car in the direction of Castleblayney.
“A short time later our colleagues in An Garda Síochána received a report of an armed robbery in the County Louth area.
“Enquiries are continuing and we are liaising with our colleagues in An Garda Síochána to establish if there is a link between these incidents.
“We would continue to appeal to anyone with any information in relation to these incidents to contact detectives on 101. Alternatively information can be submitted online using the non-emergency reporting form via http://www.psni.police.uk/makeareport/ or via Crimestoppers anonymously on 0800 555 111 or online at http://crimestoppers-uk.org .”
