The plane turned back after its captain “was alerted by a cabin crew [member] of a passenger attempting to enter the cockpit,” Malaysia Airlines said in a statement.
According to some media reports citing passengers, the man in question was holding an “electronic frequency” device or claimed he had explosives.

In an air traffic control audio recording obtained by the Sydney Morning Herald, the pilot can allegedly be heard saying: "We have a passenger trying to enter the cockpit."
Some three minutes later, he said the passenger was "claiming to have an explosive device, tried to enter the cockpit, [and] has been overpowered by passengers."
"However, we'd like to land and have the device checked," the pilot added.
