The 38-year-old singer was almost left without his luggage - which is reported to have included a pair of USD 30,000 Cartier Panther jewel-studded cuff links and a USD 500 pair of sunglasses, as well as designer clothes - when it was left unattended by his greeter and an opportunistic thief tried to grab it.
Luckily for the "All of Me" hitmaker, airport police saw the events unfold on the CCTV cameras around the area, and managed to catch the culprit before he made off with John's possessions, reported TMZ.
He then tweeted: "The bag was taken because it was left unattended. The airport police caught the person who took it (on video) and retrieved my bag.
"Thanks to the airport police/security. One could say it's been "handled". (sic)"
It is not known whether John was travelling alone at the time, or if his wife Chrissy Teigen and their 11-month-old daughter Luna were with him.
