The video warned against leaving cash, cards and other valuables in the plane's overhead compartments.

Three passengers were sitting at the front row of the plane, and failed to notice a man walking to the front of the aircraft twice during the flight.

The man took down bags from the overhead bin, and only put them back "after a while".

The three passengers later realised that their valuables had gone missing.

The video also showed a flight attendant pulling out a wad of cash from a sock. In the video, the user claimed that the money had been stashed in the sock and thrown into the back of the overhead compartment.

"Once we landed, we caught the freaking guy again trying to sneakily come out of the plane too," the TikTok added.

The victims were then taken to an interrogation room to fill in a witness statement report.

They were subsequently informed by the police that the purported thief was travelling in a group with three other people

According to the TikTok, the group of people would allegedly fly one-day transit flights, seemingly trying to steal from passengers onboard.
