In a video that has gone viral on social media, the perpetrator was seen sitting on the floor and expressing regret.

Friends and bystanders watched in shock as the man begged forgiveness.

According to the story’s details, the man waited for his friend to excuse himself briefly to use the restroom.

When his friend left the table, the man poured something into his friend’s drink and sat back as if everything was fine.

Unfortunately, someone had seen him while he poisoned the drink but kept quiet as he observed what could happen next.

It is unclear what may have prompted the culprit to consider such evil against his friend.
