Rocky tweeted about it only a few hours ago.
"Cops outside Dylan O'Brien's house right now," he simply wrote.
When a fan asked how he knew, he revealed that he was Dylan's neighbour.
However since tweeting this, he hasn't responded to anybody in 3 hours with an update, and fans are freaking out.
Some fans were also pretty annoyed that Rocky thought it was his job to let people know about the news, however, most are just wanting to know if Dylan is okay!
Dylan has been lying pretty low lately after just finishing his world tour for the final installment of Maze Runner: The Death Cure, which was delayed because of his accident.
He recently told Vulture that he "was in a dark place" after the incident, which was causing panic attacks.
Not long after, there were also reports that he and long-term girlfriend Britt Robertson had split up.
Hopefully everything is okay with Dylan!
