Stranger Things cast member Charlie Heaton reportedly isn’t being allowed into the United States because he was caught with cocaine at an airport, the Associated Press reports.

Heaton, 23, (pictured right), who lives in London, had been flying to Los Angeles for a launch party commemorating the second season of the show when he was allegedly caught with contraband.

Drug dogs reportedly detected small amounts of white powder on Heaton’s personal property that turned out to be cocaine.

The finding prompted U.S. authorities to deny Heaton entry last Saturday and deport him back to London — leaving Heaton absent from the Thursday premier launch for the wildly popular Netflix series.

Insiders fear that Heaton may be prevented from coming into the U.S. in the future, which could hinder his ability to further star in Stranger Things.

A source told The Sun: “He was not arrested. He was held at the airport for a while and then put back on a plane to London that night.”

According to that unnamed source, authorities may charge a foreign national bringing in a large amount of drugs. But if the substance is strictly for personal use, then the individual will just be banned from the country.

Heaton has previously played roles in other television shows, including DCI Banks and Casualty.

The new Stranger Things series is set a year after the first season, which has led to significant charter developments

“They start out a year later, and they’re totally sort of new people as a result of this experience that happened last year,” David Harbour, who plays Jim Hopper, told the Daily Mail.
