Just before 11 pm five masked men, one of whom is believed have been armed with a gun, forced their way into the house at Bloomfield Park.
A woman in her 20a and a four-year-old child were in the property at the time.
After asking for an individual and checking the property the masked men then left.
Chief Inspector Tony Callaghan said, “I appeal anyone who was in that area at the time and saw anyone or any vehicles acting suspiciously to contact police at Strand Road on the non-emergency number 101. Alternatively, information can be given to the Crimestoppers charity anonymously on 0800 555 111.”
