Fans of Maze Runner actor Dylan O'Brien have mounting concerns for his wellbeing, as the rising star has not been seen or heard from publicly in the four months since a dramatic on-set accident.
O'Brien was hurt on set and reportedly sustained multiple broken bones after being hit by a car while filming Maze Runner: The Death Cure in Vancouver, Canada in March.
The 24-year-old actor plays Thomas, the lead character in the franchise.
A week later, the franchise's director Wes Ball gave fans some reassurance that the actor was doing OK. He tweeted: "It's scary seeing your friend get hurt, but fortunately, Dylan is going to be just fine. After a few weeks of rest and recovery he'll be back up and running to finish our adventure together."
Then, in April, a fresh statement from Fox, which seemed to suggest that O'Brien's injuries were more serious than first thought:
"The resumption of principal photography on Maze Runner: The Death Cure has been further delayed to allow Dylan O'Brien more time to fully recover from his injuries. We wish Dylan a speedy recovery and look forward to restarting production as soon as possible."
That was almost three months ago - and there's still been no public sighting of O'Brien since the accident whatsoever.
His one active social media channel, Twitter, has not been touched since mid-March.
With no updates on O'Brien's recovery or indeed even the seriousness of the injuries he sustained, fans have been left in the dark about the much-loved lead actor of a franchise that has already made more than $650 million worldwide across its first two films.
The lack of news has fuelled speculation that the third instalment will not hit its target release date of January 12, 2018.
While confusion about O'Brien's wellbeing remains, some reports suggest his injuries were more severe than initially thought.
In a statement obtained by Sugarscape, WorkSafeBC stated that O'Brien was pulled to the ground by his own safety vehicle while filming a stunt.
The report also stated that the actor was dragged under the vehicle, suffering concussion, facial fractures and lacerations.
