Health concerns were on artist Danai Ussama's mind when he returned to Thailand last month from a trip to Spain.
He noticed that he and his fellow passengers did not go through medical checks after arriving at Bangkok's airport, and thought it worth noting on his Facebook page.
The airport authorities denied it, lodged a complaint with police, and he was arrested at his gallery in Phuket for violating the Computer Crime Act by allegedly posting false information -- an offense punishable by up to five years imprisonment and a fine of 100,000 baht ($ 3,063).
Danai told The Associated Press that his Facebook post, though public, was really meant just for a small circle of 40 to 50 people. Instead it went viral.
He believes the government is afraid its opponents would use his observation as proof it was failing the fight against the coronavirus, and acted against him as a warning to others.
As governments across the world enact emergency measures to keep people at home and stave off the pandemic, some are unhappy about having their missteps publicised. Others are taking advantage of the crisis to silence critics and tighten control.

"If I had known that I would be in so much trouble like this, I wouldn't have written it. I have never been arrested nor gone to court before. I was handcuffed and slept overnight in a police station cell. I was devastated, actually. It affects my family and myself. But deep down inside, I would have wanted to write it anyway," he said.
