Mr Gosling was charged on August 30 and has since been held at Singapore's Institute of Mental Health. His Singapore-based lawyer Gloria James said Mr Gosling had handed himself in to local police. She said in an email to The Age and The Sydney Morning Herald that before being taken into custody Mr Gosling had indicated to his lawyers that he would plead guilty to the offence. However, she said that she had been unable to confirm this with Mr Gosling because she had not been allowed access to him while he was being psychologically assessed. Mr Sunee was about to eat dinner with his family at a housewarming when the bottle hit him on the head.

Tributes have flowed for the grandfather on social media, with his nephew Mohammed Nafis describing him as a "fatherly figure" and a "good man". He told The Age on Tuesday the last few weeks had been "draining and painful" for the family but said they were "taking each day as it comes". He also said those who knew his uncle were calling for Mr Gosling to be handed a significant punishment, but as Muslims they preached forgiveness.

"There is no need for us to now turn it into bitterness by rejoicing in his plight and predicament," he wrote in a widely-shared post to Facebook. "Being vengeful just means stirring more hatred and truly there is already enough of that going on around the world. "Let it be known that we take pride in ourselves as Muslims who are raised to never do onto others what we do not want others to do onto us. "We may have lost a fatherly figure but we certainly do not want to take that same role figure away from his family." Last week, Mr Gosling's mother Pam said her son was "loving and caring and hasn't got a malicious bone in his body". "We will support him all the way, we will always be there," she told Seven News.

"We will get through because we are strong and he's strong." Mr Gosling is scheduled to appear in court on September 17.
