The Solomon Islands High Court has sentenced a Vietnamese national to four and a half years for unlawful wounding of a crew member of a fishing vessel.

Van Thang Nguyen, who is currently serving a life sentence for murder will serve the four and a half years concurrently with his first sentence.

Nguyen was charged with the death of a crew member in February in 2012. He also stabbed another victim on the shoulder.

Nguyen and the victims were celebrating the Chinese New Year when an argument broke out which resulted in the death of one crew member.

Nguyen stabbed one of the victims in the eye and the other on his shoulder. The one he stabbed in the eye died shortly after the incident.

It is understood that there is no arrangement for Nguyen to serve his sentence in his country.
