Police in a Mexican border city on Wednesday said that a drone filled with drugs crashed into a supermarket parking lot.

The Associated Press reported the illicit methamphetamine-filled drone fell Tuesday night near the San Ysidro crossing at Mexico's border with California. The flight had six packets of the drug, weighing over six pounds.

Tijuana police spokesman Jorge Morrua said authorities were alerted right after the drone crashed into the supermarket building. He added that they are investigating where the drone came from and who was controlling it.

Officials are also investigating where the drone found at the U.S.-Mexico border was headed, according to BBC News.

In November, people were arrested after a remote-controlled helicopter was used to carry tobacco into a state prison in Georgia, according to BBC News.

In April, officials in South Carolina found a drone carrying cellphones, marijuana and tobacco right outside a prison, ABC News reported. One person, Brenton Lee Doyle, was arrested in connection with the contraband-filled drone found outside Lee Correctional Institution in Bishopville on April 21. He was charged with drug possession and trying to give contraband to inmates.

"As technology gets more advanced, we have to find more advanced ways to fight that," spokeswoman for Lee Correctional Institution Stephanie Givens said, adding that the drone was designed to fly for long periods of time.

A drone carrying contraband was found in Australia as well in March.

"We understand that the regulator is doing its best to try and combat that," secretary of the Australian Certified UAV Operators Association Brad Mason said about the illegal use of drones. "But, unfortunately ... they are so easily available and so cheap to buy these days that anybody can buy one and anyone can go out and operate one."

Other methods of smuggling have included catapults, ultralight aircraft and tunnels.
