"Dancing with the Stars" alum Maksim Chmerkovskiy revealed he was arrested as he tried to flee Ukraine amid the ongoing war with Russia.

Chmerkovskiy ensured fans that he is "all good" following his arrest in an almost five-minute video shared to his 1.1 million followers. Later Monday the choreographer revealed he made it onto a train, which he says, is hopefully heading to Warsaw, Poland. According to Chmerkovskiy, a train to Lviv was not possible for him.

"The situation at the train station is insane. AT first it feels manageable, but it gets A LOT worse when it comes time to actually board the train. Long story but all I can say now is that I'm a big man with nothing but a backpack it's TRAUMATIZING," he said.

Chmerkovskiy described the capacity of the train "wagon" as being 30 people normally, but claimed they were told the "wagon" would need to fit 135 people. 

"Walkways are packed," he revealed. "People everywhere. It's sweaty and claustrophobic."

Chmerkovskiy has kept his social media followers updated during his time in Ukraine.

"[There’s] a lot of fighting everywhere," Chmerkovskiy said in a video update earlier Monday. "Streets are crazy. At one point I got arrested. … But all good, promise."

"That was probably the least traumatizing moment in this whole thing as far as Ukraine is concerned, but for me, it was a reality check."
