The Director of Public Prosecutions is appealing the sentence imposed on the owner of an aviation company who attacked and sexually assaulted a woman in Dublin almost two years ago.

Anthony Lyons, 51, from Griffith Avenue in Dublin was jailed for six months after he was convicted of the attack on 3 October 2010.

Mr Justice Desmond Hogan sentenced Lyons to six years in prison, but suspended five-and-a-half years of the sentence.

Lyons had pleaded not guilty to the offence and claimed he carried out the attack because he was on cholesterol medication at the time.

The Courts Service confirmed that the DPP lodged papers with the Court of Criminal Appeal this afternoon.

The DPP is appealing the sentence on the grounds of undue leniency.
