He stopped someone from illegally filming.

BTOB‘s Changsub is gaining attention for his honorable actions.

In the 60th episode of ootb STUDIO‘s “Jeongwaja” series, the K-Pop idol visited a police university. He recounted the time he stepped foot inside a police station, not because he committed any crimes, but because he was the reporter of one.

He explained that the incident happened in a men’s bath house. Here, he and his friend who was a dancer found a foreigner filming other visitors illegally.

I went to a bath house and some foreign guy was filming with a hidden camera in the men’s bath house. There was a dancer friend with me who discovered it.

They were not afraid to approach the perpetrator and quickly took him to the police station. Changsub had to return a few days later after evidence against the foreigner was found. The K-Pop idol was then asked to give his testimony as a bystander.

He saw it and caught him so we took him to the police station. A few days later, after forensic analysis, [it was found that] he was holding the camera [under him] so I went to the police station for questioning. The investigator was writing things down and asking questions, ‘Age, name, how and where did it happen?’

Fans reacted positively to the news, taking to social media to exclaim how much they love BTOB because of how they are “not scared to do the right thing,” adding that they’re “the hope of humanity.”
