Lee Jong-suk returned home to South Korea after being detained in Jakarta, Indonesia, for about two days.
Lee visited Jakarta on November 3 as part of a fan tour, which included visits to Japan in August, and Taiwan and Thailand in September.
The next day he was supposed to board a plane for South Korea, but Leeu and his team were not given a departure.
The closing of an actor in Jakarta was published on Monday in Instagram, saying: "All staff members and I are currently attached to Jakarta. We have been arrested since yesterday." The job has since been deleted.
Lee's agency A-man Project offered an update on the situation through an official statement released Tuesday morning.
"The foreseen return of Lee Jong-suk to South Korea is postponed due to incomprehensible handling by the management and (local branch of the Korean event organizer). Yes 24. Fortunately, the actor is currently on board a plane with the help of the Indonesian embassy," read the statement.

The statement attributed the reason for detention to illegal business activities Yes 24, which includes the failure to meet the obligation to pay taxes and the failure to fulfill the visa services for employment.
It was also stated that the local contractor did not provide a consistent explanation of the situation.
"We were first informed that 24 local governments retained unpaid taxes, a process in which the passports of actors and staff were confiscated," the statement said. "However, local news reports later reported that Yes 24 did not apply for a short-term employment visa."
The A-man project announced that the legal action will be taken through the law firm Iulchon, based in the southern district of Gungnam, Seoul.
"The agency will take legal actions through Iulchon and the lawyer responsible for management and the local promoter. All legal measures will be dealt with (the law office)," she said, apologizing for "causing concern."
Lee was the youngest male model to walk on the runway at Seoul's Fashion Week in 2005. The model died on screen in 2010, leading the lead roles in the TV series "Prosecutor's Princess" and the horror movie "Ghost." As an actor, he saw his breakthrough with a series of hits "Secret Garden", which was broadcast from the end of 2010 to the beginning of 2011.
