Jakarta. The management of Safari Park in Bogor, West Java, is tracking down a male visitor who drew outrage on the internet after he was caught on video feeding a hippo plastic waste.

The good news is that the management has an important lead from the license plate of the vehicle and is demanding that the irresponsible visitor make a public apology.

"We have identified the license plate of the vehicle carrying that person. We urge him to make a public apology to teach a lesson to other visitors about complying with the standard operating procedures at the Indonesian Safari Park," the park’s spokesman Alexander Zulkarnain said on Saturday.

"We have collected information from our guards and security cameras at the park. Guards told us that this particular visitor had been reprimanded several times for opening the window in the tiger area," he added.

Alexander said animal abuse could lead to legal consequences because all animals at the sanctuary are protected by wildlife law.

He added that the hippo has been examined and is in healthy condition.

Thursday’s incident went viral on the internet after an amateur video from another visitor circulated on social media, depicting the man throwing plastic waste into the hippo’s open mouth.

He also poked the nose of a deer with a carrot.
