An Indian woman was detained after she threatened to hijack a Malaysia Airlines flight during a domestic flight from Kuala Lumpur, a news report said on Thursday.
The 35-year-old woman boarded the plane late on Wednesday with two children, aged one and three.
In the middle of the one-hour flight, which was headed for the northern Penang state, the woman went to the cockpit and demanded to be let in, the Star daily quoted sources as saying.
The suspect threatened to "take over the plane" but was later convinced to return to her seat by aircrew, it said.
Upon arrival at Penang, airport police detained the suspect along with the two children for questioning.
