Shocking moment wife sparks massive bar brawl when she attacks her husband and his mistress after catching them drinking together

THIS is the shocking moment a spurned wife attacked her hubby and his mistress after she caught them together in a bar.

CCTV from a Brazilian bar captured the extraordinary exchange as the affair was exposed.

A man can be seen enjoying a beer with two women at the establishment in Rio Verde.

Out of nowhere another woman, thought to be his wife, bursts into the bar and slaps the man across the back of the head.

With the man reeling she then reaches across to the woman sat next to him and grabs her by the hair, slamming her face into the table.

As the man attempts to separate the two women, his wife flings a chair at his mistress.

Bewildered onlookers stream out of the bar as the fight escalates into a street brawl.

Suddenly another woman, thought to be the wife's friend, joins the fray attempting to bottle her pal's love rival.

A fellow drinker in the bar was forced to tear himself away from his quite beer to step in and protect the mistress.

Meanwhile the husband and wife were battering each other in the street before bystanders managed to wrench them apart.

After the bust-up the husband returned to the bar after having his shirt torn from his back.

The video of the incident, which happened on February 19, was posted online last week and has since been viewed more than 100,000 times.
