A man, who according to am.com.mx is supposed to be a tourist, bought a bottle of acid in a corner store in Cancún Quintana Roo, and spread the liquid on the sidewalk in front of the aforementioned store.
In the place was an indigenous girl who was barefoot and sitting down outside the store. The girl had to get up quickly to avoid being burned with the acid.
According to the video that went viral on social networks, the subject intentionally spilled the muriatic acid to make sure the girl did not return to the place.
