A New Zealander wanted by Interpol for skipping bail in Singapore while charged with assault has returned and handed himself into police.

Former junior New Zealand basketballer, Robert Dahlberg, 35, was involved in a fight in 2010 and was charged alongside two other expat men in July 2011.

He fled Singapore in September last year.

He returned to Singapore voluntarily on Thursday accompanied by his father.

"I return to co-operate fully with the Singapore authorities and abide by the due process of the case before the Singapore courts," Dahlberg said in a statement.

"I am very sorry for the inconvenience caused to the Singapore police whilst I was outside Singapore."

Dahlberg appeared in Court yesterday, charged with voluntarily causing grievous hurt and rash act causing hurt.

He will next appear in court for sentencing on September 21.

If found guilty, Dahlberg could face up to 10 years in jail and caning.

His father, Bill Dahlberg, said the family were standing by him and supported his decision to return to Singapore.

"As a family, we still can't quite believe this is happening but are supporting each other and doing all we can to ensure Robert is supported as much as he can be in Singapore."

Briton, Robert James Springall, 25, also fled in December and the two men were subsequently put on Interpol's wanted list. Springhall is still at large.

Australian Nathan Robert Miller, 36, pleaded guilty and was sentenced to three weeks  jail in February this year.
