A man was arrested for throwing coins at a plane's engine but says he only did the deed for good luck.
The superstitious 30-year-old - who is only known as Xia - claims he did the questionable stunt because he thought it would bring good luck and ensure a safe flight.
However, security officials and police did not agree with his actions, which he carried out while boarding a Hainan Airlines flight to the city of Urumqi in north-western China.
Xia said it was the first time his four-month-old daughter was flying on a plane, so his mother-in-law advised he should throw some money at the aircraft for good fortune.
He was detained in Wuhan for 10 days - while his wife continued to Urumqi with their daughter.
The incident caused the flight to be delayed for 40 minutes.
