A helicopter with five people on board went missing in Indonesia on Sunday and is believed to have crashed. 

The helicopter had taken off from Indonesia's Samosir island and was destined for Medan, the capital of Sumatra island. 

The Eurocopter EC-130 was carrying three passengers and two crew members and went off the radar just 17 minutes into the flight, according to The Associated Press. 

The chopper reportedly had enough fuel only to fly for three hours. 

"Residents said they saw a helicopter flying low over Lake Toba and heard a crashing sound," a local rescue official was quoted saying by SBS.

The incident is the latest in a series of tragedies related to plane and helicopter crashes in Indonesia. 

In June, an Indonesian air force plane crashed in a residential area and killed more than 100 people. 

Earlier this month, a small aircraft with ten people on board went missing and was found crashed, with all on board declared dead.
