People in the north Roscommon area and surrounds are being advised to check their Euromillions tickets from last week as the winner of half a million euro still has to come forward.
The winning ticket was bought in Healy's Xpress Stop at Ballyfarnon in the days leading up to Tuesday of last week , the 6th of October.
The half million was a prize in the EuroMillions Lotto Plus Draw on the 29th but no one has claimed the prize so far.
The National Lottery Office has said its early days as yet, but they are encouraging people to check their glove boxes, and coat pockets in the meantime, just in case.
