"Not bad, you did very well," Huo Liangze nodded with satisfaction and promptly took out his phone to call the head of the airport police station. "Chief Zhou, I've discovered something. A person from out of town has been kidnapped. I'm sending you the location. Hurry up and have someone check it out. If you're too late, there might be serious trouble."
"What! Kidnapping?" Gao Yuanzhong was stunned.
Restricting someone to a certain place can be described differently.
Illegal restriction of personal liberty, unlawful detention, and kidnapping are the three forms it can take.
The crimes are different for each of these situations, with the first two being less serious, but kidnapping is a much more serious charge.
It's possible to interchange these charges, depending on what one says and does.
There are many cases where kidnapping is downplayed to illegal restraint, and there are many cases where simple restraint is escalated to kidnapping.
