Four Engineering Students Play Prank with DIY Gas Cylinder Device, Fire from Sunroof While Driving Down Street, Terrifying Residents

Four engineering students caused a commotion by constructing a homemade gas-pressurized launcher, opening a car's sunroof, and firing it playfully down the street, terrifying residents and causing a woman to fear she was under attack. A 30-year-old woman named Por filed a report with Muang Nonthaburi police stating that on April 26 at 4:00 AM, while riding her motorcycle from Soi Liang Muang Nonthaburi 5 onto the bypass road, a white Ford Everest followed her and she heard a gunshot-like sound once, then again at a turning point, making her fear for her safety.

On April 29 at 3:30 PM, Muang Nonthaburi police investigation officers summoned three 17-year-old male engineering students from the industrial engineering department at a university near Rama VII, along with a homemade bird-scaring launcher and a spray bottle containing 100 percent alcohol. One of the four students was unable to attend due to illness, though a parent was present to hear the questioning. After investigating the scene, police determined all three were responsible.

The students explained they had been at an older brother's house in Bang Sri Muang that day. On the way back, in a playful mood, they used the homemade bird launcher they had made for bird control at the residence, pressurized it with gas, opened the sunroof, and fired it repeatedly along the route. They admitted they had created the device based on a social media tutorial intending only to scare birds at home, not to threaten anyone, and acknowledged their recklessness and foolishness.

Officers then brought the victim to speak with the students. After mutual understanding was reached, the students apologized to the victim and promised not to repeat the behavior. Police filed a record of the incident before releasing them.
