A Mexican gang tortured an alleged rapist by stripping him naked in the street before making a pit bull eat his genitals.
The unnamed man in his 30s was set upon after allegedly sexually attacking a woman in Mexico City last month.
In horrific footage, said to be released as a warning to others, the man is seen writhing on the floor while handcuffed and surrounded by men,
A white pit bull terrier with brown markings then begins mauling the man's genitals.
The victim is heard screaming ''stop, leave me now, leave me'' while the group watch. One of the gang then covers his mouth with a rag to stifle his cries for help.
A second dog, a brown pit bull, appears but does not join in.
Footage taken by one of the attackers shows how the alleged rapist was castrated by the ravenous dog, leaving nothing but a gaping, raw wound.
Video of the savage torture emerged last month. It was reported in local media that a criminal gang had caught the man after he allegedly raped a woman.
The attackers are said to have made the video public as a warning to other would-be attackers in the crime-ridden hell-hole.
Local media reported that in recent years ''methods of torture by Mexican criminal organisations have increased their level of cruelty''.
They claimed that such attacks were becoming ''increasingly frequent'' and claimed dozens of women are raped every day.
''One of those women, supposedly, was raped by the protagonist of the video,'' reported DonDiario.
It is not known if the man in the clip survived.
Mexico has the world's highest murder rate with 17,000 killed in the first half of this year - the highest levels in its history.
Astonishigly, that figure does not include drive-by shootings, kidnappings, extortion and other serious crimes, many of them part of cartel and gang violence.
In 2015, the rape rate for Mexico was 12.6 cases per 100,000 population though the actual number is likely to be much higher as many go unreported.
