Suddenly, the experienced service dog let out a low, angry growl, attracting the attention of the passengers.
The pale, thin woman held the stroller’s handles but her hands were shaking.
“Take that dog away from my baby,” she yelled.
Officer Andre tried to pull Luna away from the stroller, but she didn’t obey. This was the first time in three years the service dog to fail to respond to her handler’s command.

Rather than backing off, Luna stepped closer and pulled the blanket and what appeared from under it shocked everyone.
There wasn’t a baby there but a thermal bag with labels written in Russian and Chinese and symbols of biological hazard. Inside, there were shiny containers that released strange odor.
Officer Andre quickly grabbed the woman by the arm and pulled her aside. He alerted the antiterrorist team of the incident.
“What is this?” Andre asked the woman.
