A man sought in New Zealand in an inquiry into the burning death of his wife has been detained in Fiji after an international manhunt, police said Tuesday.

The man was located by police in the Rakiraki District in western Fiji on Monday night along with his four-year-old son, Detective Senior Sgt. Nigel Keall said. Police have not released the man's name.

The burning body of the man's wife, Ranjeeta Sharma, was found by a motorist last Thursday night beside a roadway in a rural area near Huntly in northern New Zealand. A homicide investigation was launched when an autopsy showed that the 28-year-old nurse was alive when she was set on fire.

Sharma's husband is "a person of considerable significance" in the investigation, police said.

The man, who has family ties to Fiji, flew to Fiji with the couple's son the day after his wife's body was discovered, police said.

New Zealand sought the assistance of Fiji police in locating him, and expressed concern for the wellbeing of the son. Fiji and New Zealand have an extradition agreement, a Foreign Ministry spokesperson said.
