(CNN) – A week after Malaysia Airlines Flight 370 vanished, the investigation shifted to passengers and crew after data showed the plane deviated due to deliberate action, Prime Minister Najib Razak said Saturday.
“Malaysian authorities have refocused their investigation on crew and passengers aboard,” Najib told reporters. “Evidence is consistent with someone acting deliberately from inside the plane.”
Najib stopped short of calling it a hijacking, saying investigators have not made a final determination.
“Despite media reports that the plane was hijacked, we are investigating all major possibilities on what caused MH370 to deviate,” he said.
