The Bangkok Post reports that guards at the Khao Bin Prison in Thailand took possession of what appears to be a DJI Phantom drone laden with cell phones and accessories. The drone was snagged on a tree limb inside the prison compound.

Taped to the drone were two Nokia cell phones, four SIM cards, a pair of Bluetooth devices, and headphones. Also attached to the aircraft was what appeared to be a system on a board—about the size of a Raspberry Pi computer. The gear was concealed in a plastic bottle.

In addition to its illicit cargo, the quadcopter was equipped with a GoPro video camera and a Wi-Fi signal range extender to allow the drone to be remote-controlled from a greater distance, based on analysis of the photos published by the Post.

According to Thai officials, the phones would have been worth “millions of baht” within the prison’s walls (one million Thai baht is roughly worth $30,000). The operator of the drone was not captured, as he or she fled after the drone became ensnared. Police are now canvassing drone sellers for potential suspects, Danai Suspin, director of the Prisoner Counsel and Development Division at Khao Bin, told the Post.
