Reward of £1,000 has been offered to find the man who disgustedly smirked as he threw dog off a tall building.
This horrifying 33-second video shows a man grinning into the camera as he picked up a dog from its leash.
He then launches the distressed animal into the air before hurling it off the terrace.
Desperate cries can be heard as the defenseless dog hits the ground, while the suspect can be heard nonchalantly talking in the background.
Heartbreakingly, the dog's injuries were too severe and the animal was not able to be saved.
Though it is unclear who captured the video, it is believed to have taken place in Tamil Nadu, India.
Reports suggest the horrendous incident took place two weeks ago and that police have identified two possible suspects.
The video was posted on Facebook by Prashanth Rangaswamy on July 4 and has already had more than 100,000 views.
Prashanth uploaded the clip with the caption: "Dog lover and dear friend Arvind Vimal David willing to reward 10,000 rupees to the person who can identify this heartless b******. Faint hearted please do not watch. Please share maximum. Humans are becoming the worst animals."
Humane Society International announced on Facebook a Rs. 1 Lakh (£1,118) reward would be issued to whoever is able to identify the location and the main in the video.
According to recent social media updates, a final year student at Madha Medical College, Tamil Nadu, has been identified as the suspect.
