Authorities say a child opened a LEGO set to find it was filled with $40,000 worth of methamphetamine.

The Statesboro Herald reports three women from Georgia bought a box that appeared to be filled with a variety of classic LEGO bricks while at a consignment shop in Charleston, South Carolina. They gave it to a child in Statesboro, Georgia, who opened up the gift and found three pounds of meth inside.

The women immediately contacted the Bulloch County Sheriff’s Office about the drugs, according to WNEP-TV. Deputies said they collected the meth and contacted the Drug Enforcement Administration.

The DEA told CNN the box may have been purchased in a storage auction before arriving at the consignment store, “without anyone questioning its contents.”

Jim Riggs, an investigator with the Bulloch County Sheriff’s Office, told the Herald that it may have been initially mailed to a wrong address or an abandoned place. Unclaimed packages are sometimes auctioned off “sort of like ‘Storage Wars,'" he said.

“A Bulloch County citizen reported to the Sheriff’s Office that they purchased a box of Legos at a consignment shop in South Carolina,” the office said on Facebook. “Upon returning home and opening the box they discovered the box contained a quantity of methamphetamine instead of Legos. The meth was collected by Deputies and turned over to investigators who contacted the Drug Enforcement Agency for assistance. The DEA believes the package was possibly purchased as part of some type of storage auction and eventually made its way to the consignment company without anyone’s knowledge."

No charges have been filed.
