A Sydney man who was jailed for savagely beating Corkman David Keohane in August 2008 has had his sentence over the assault and robbery of another man reduced.

The Corkman was discovered lying on the ground near the intersection of Brook and Kidman Street at Coogee at about 3am on Saturday, 9 August 2008.

He was resuscitated by a passer by and taken to hospital.

Mr Keohane suffered extensive injuries during the attack, including among others a lacerated tongue and breaks to almost every bone in his face

He was treated at Prince of Wales Hospital before being taken back to Ireland in a coma by his family in September 2008.

After 281 days unconscious, he came to on 17 March 2009. Mr Keohane, who  suffered brain damage, remains in a wheelchair and is under the constant care of his family.

In April 2010, Sydney man Thomas Isaako was sentenced to a total of 14 years in prison for the violent assault of Mr Keohane and the aggravated robbery of Ben Wang.

The Court of Criminal Appeal in New South Wales yesterday cut by two years the portion of the 23-year-old’s sentence that relates to the robbery of Mr Wang.

Mr Wang was beaten and robbed by Isaako near Riverwood Railway Station nine days after the attack on Mr Keohane.

Mr Wang’s backpack was stolen, which contained a digital camera, a new iPod and an electronic dictionary. He also took the victim’s mobile phone.

The three judges of the Court of Criminal Appeal noted that Isaako’s appeal did not seek to alter the sentence handed down for the attack on Mr Keohane.

“This is not surprising given the savageness of the attack that was involved,” they noted in their written judgment, made public yesterday.

However, the judges found that the sentencing for the offence against Mr Wang “was manifestly excessive”.

It was reduced to a minimum of four years, with Isaako eligible for parole on 15 September 2020.
