Confusing M'sian news on "stolen" jet engines

Quoting intelligence sources, a news report of the New Straits Times claimed that the missing jet engines have been "transported to a US-sanctioned Middle Eastern country" but the police has reportedly said that the parts have been "traced to Argentina". Since the New Straits Times is a mainstream media which projects an authoritative image, the question of whether it or the police is to be believed is pertinent. Is the New Straits Times or police more authoritative on this matter? The New Straits Times was the first media that reported the scandal.
