The violence against Prayoga was recorded by a video, which later became viral in social media.
From the video, Prayoga was seen dragged and smothered by some members of Mobile Brigade Police to a certain place, but he managed to release himself.
Prayoga remarked that the incident took place at 3 pm when a member of the Mobile Brigade Police, Adam, approached and stared at him as he was about to get into an ATM booth at the Jakarta Convention Center.
"I thought I have done something wrong, and I asked Adam what it was," Prayoga said.
"But then, Adam and his three other friends held me and tired to slam me onto the floor as if I were a thief," Prayoga went on.
This situation of the violence was recorded by a video, including the sound of loud voice from unscrupulous Mobile Brigade officers.
Prayoga said he was traumatized with the incident, as one of the officers pointed a gun at him, challenging him to fight, and uttering intimidating words.
But after that the situation began to calm down when a senior Mobile Brigade member came and tried to mediate.
