This weekend, David Morales was arrested by Japanese authorities for "suspicion of smuggling" 0.3g of MDMA, and now faces up to seven years in prison.

The detainment happened as the Grammy winner traveled to Fukuoka club Bijou for a performance scheduled for October 6th, and a customs official found just five granules of the drug in his carry-on baggage.

“He was arrested for allegedly violating the law on narcotics and psychotropics control,” a police spokesman told news agency AFP.

Morales denied the substance was his, saying someone "might have tried to frame (him).”

Now fans are hoping to raise further awareness for his detention with the #FreeDavidMorales hashtag, claiming the Japanese government is being "brutal" in their indefinite incarceration of Morales.

Japan has extremely strict drug laws. The penalty for possessing even a small amount of class A drugs for personal use can result a seven year prison sentence and a three million yen ($26,000) fine.

So far the hashtag has mostly been shared by fans. Though legendary DJ Danny Rampling has also joined in his support.

As for Morales, the situation so far remains the same, with his representative commenting on Monday: "We’re unable to comment at this time, but will share further information with you as and when we’re able to do so.”

Perhaps if #FreeDavidMorales begins trending, the situation might change.
