LOS ANGELES, Dec. 27 (Xinhua) -- The remains of six people onboard a helicopter that crashed on its way back from a sightseeing tour in Hawaii have been recovered, local authorities confirmed on Friday.

Seven individuals -- one pilot and six passengers, including two children -- were on the flight.

Local authorities said they will return to the site of the wreckage on Saturday to search for the seventh set of remains.

The crash site of the helicopter has been confirmed in Koke'e State Park near Nu'alolo Cliff Trail on the Kauai island, according to a release of the Kauai County.

"There are no indications of survivors," said Kauai Fire Department Battalion Chief Sol Kanoho at a press briefing.

Kanoho declined to release any details about the victims, but said in addition to the pilot, there were two groups of passengers on the chopper.

Multiple agencies have been engaged in the massive search for the aircraft by air and sea since Thursday night. But by about 3:30 p.m. on Friday (0130 GMT on Saturday), fog and poor visibility forced Kauai firefighters to suspend their search for the seventh person until Saturday morning.

According to local media reports, the U.S. Federal Aviation Administration confirmed the crashed helicopter was a Eurocopter AS350 B2. Its safety record was not immediately available.

Investigators of the U.S. National Transportation Safety Board plan to arrive in Hawaii over the weekend.

The wreckage of the tour helicopter was found in a mountainous region earlier Friday.
