X Factor judge Louis Walsh has denied an indecent assault on a young man in a nightclub toilet.

The star, 58, is accused of molesting a 24-year-old man after meeting him in a Dublin bar following a Westlife concert on April 10th.

The man claimed Walsh groped his private parts after they struck up a conversation in the bar of the Dublin’s Russell Court Hotel.

Police are studying CCTV from the hotel’s bar and nightclub, where the victim claimed the assault took place.

Walsh told the Sun: “The allegations made against me are wholly false and with no foundation.”

He added: “I will happily cooperate fully with the police and am 100 per cent confident that after a full investigation I will be fully exonerated.”

A police source said officers were investigating and Walsh may be interviewed if there is a case to answer.

The alleged victim, described by the newspaper as a single dad, has not commented.
