Customers at a bar were given an almighty fright when a drunk monkey snatched a kitchen knife and started chasing them after downing leftover rum.
The little capuchin - a breed known for their temper - apparently turned aggressive after helping itself to dregs of rum in the bar.
Picking up the foot-long blade, the animal reportedly set about terrorising punters at the bar in Paraiba, Brazil.
However, according to reports, it only went after the men in the pub, leaving the women to drink in relative peace.
It is said to have left the area shortly after.
The owner of the bar called firefighters, who after some searching and manouvering were able to find and capture the capuchin.
Lieutenant Colonel Saul Laurentino, fire chief, said: "It was a bar staff oversight that ended with the monkey drinking some rum and taking the knife. According to news reports, firefighters released the animal into a nature reserve, after the incident earlier this month.
But it had to be captured again after terrorising residents.Read more :It's unknown whether it will be released into the wild or kept in captivity.
