The police are investigating the circumstances of a video circulating online, which shows a man being physically assaulted by a group of men, in what appears to be a jail cell.

In the video, the group of men can be seen pouring flammable liquid on the man.

They also repeatedly stomped on the man while shouting homophobic slurs and expletives at him.

The man can be seen lying on the ground helplessly crying.

The video ends with the group of attackers hitting the man on the head and knees before walking away.
