The boy, surnamed Chen, was accompanied by his father when he surrendered himself to police in south China’s Guangdong Province on Tuesday evening.
Earlier the same day, flights CA4111 from Lhasa, capital of the Tibet Autonomous Region in southwest China, to Beijing and CA1578 from Nanchang in Jiangxi Province to Beijing were aborted shortly before take-off.
Flight crews evacuated passengers before a thorough check was made of both aircraft and their passengers and luggage.
It was several hours before the calls were deemed to be hoaxes and the flights eventually took off at around 8:15pm.
CCTV reported that the boy has long suffered from mental problems and had been admitted to Zhongshan City No.3 People’s Hospital three times (hopefully not against his will).
Hoax calls have become more frequent this year with more than 10 affecting domestic carriers.
In previous incidents, some callers made threats in protest at delays or poor service. Others were said to have tried to disrupt flights for personal reasons.
In one case, a tour guide claimed a bomb was planted on a plane in order to delay the flight, as the tourists he was in charge of were late.
In another case, a young man used the same method to stop his girlfriend from leaving him. Other cases are said to have stemmed from sheer boredom.
