An unemployed dance teacher, who falsely accused Louis Walsh of groping him in a nightclub, has lost an appeal against his six month prison sentence.
Leonard Watters pleaded guilty to making two false reports to police that the X Factor judge sexually assaulted him in Dublin nightspot Krystle in April 2011.
The 25-year-old also went to the The Irish Sun newspaper with his story.
But within days Watters was shown CCTV footage from the club that disputed his claims and he admitted he had made up the allegation.
He was arrested at his home in Navan, Co Meath, and charged before publicly apologising to Walsh for the unfounded claims
Judge Katherine Delahunt told Watters she was increasing his sentence to 11 months, but suspended the last five on condition he co-operates with probation services and enters an alcohol rehabilitation programme.
She said that while his alcohol addiction may explain his false claims on the night, it could not account for the charade he kept up for the next two months until he was confronted with evidence.
