(Sydney, Australia) Australian police say they have cracked a “highly sophisticated” international drug smuggling ring that used containers labeled “gay lube oil” to hide illegal and potentially dangerous drugs.

In all, 150 containers were seized when customs agents became suspicious. Tests on the contests showed the containers held performance- and image-enhancing steroids, including testosterone and deca durabolin.

Police said it was doubtful the drugs were destined for gay communities, but rather for athletes.

The drugs require a ministerial permit for their use. 

“These substances have the potential to cause serious health risks,” the government said in a statement.

Police said they have search warrants to hunt for additional containers throughout the country and are working with Thai authorities to track the original source.

A number of arrests already have been made and police said Wednesday that more are expected.  If convicted, the penalty for smuggling drugs into Australia is five years in prison and a fine of up to $110,000.
