The brother of a footballer who was left brain damaged in a brutal attack is using his singing talent to raise funds to further the family’s quest for justice over the assault.

Adam Hughes, 26, sang at a Thornton Heath talent show to raise funds for his brother Robbie, 29, who survived four life-saving operations to his skull after he had his head stamped on outside a Malia nightclub on June 17, 2008.

The former boy-band member hopes the money will help pay for the £20,000 legal fees to make sure his brother – a former Sutton United and Croydon Athletic player – gets justice over the attack.

Adam, who used to be in boy band Kucci, sang with rapper David Hooker, from Wallington, at Thornton Heath Festival to help raise money for the family’s campaign, A Pound for Justice.

He said: “What we have been through as a family is kind of a fatality; the brother I have now is not the Robbie I knew – he’s there in person, but not there mentally. The cost of the legal fees to make sure Robbie is represented properly in court keeps rising and we as a family are struggling to meet the cost ourselves.”

Five men accused of the attack are currently on bail.

The Hughes need help to meet the cost of paying for a Greek lawyer. Unlike the accused they cannot claim legal aid.

Adam, a health and social care student, sang with Mr Hooker, 22, whose stage name is Mighty Milkshake, due to his pale features and childhood milk round. The pair dedicated the song Mutual Understanding to Robbie, who turned 30 this week.

Mother Maggie Hughes said: “It is expensive for victims to get justice and we are just really desperate for people’s help.”
