VIDEO: Angry brother beats up sister’s boyfriend for cheating

There is an unspoken verbal contract that says brothers can make fun of their sisters but will never let someone else tease them.

Some will even tell you that no matter how strong you are, you cannot mess around with their sister.

One man learnt this the hard way after he was caught cheating on the girlfriend by the brother.

In a video seen by Ureport, the unidentified man is being slapped for sleeping around while dating Sparta’s sister.

He is slapped and punched severally by Sparta who is visibly enraged and wants to teach him a lesson for not being able to zip up his trousers.

“Niangalie! hukua unajua nini? Amka. Mbona unatumia sister yangu?

“Uko na madame wangapi? Mbona unakujia sistangu?,asks Sparta amid a number of slaps.

The victim pleads for mercy and apologises but it falls on deaf ears.

“Sparta please, Sparta wacha izo,” he begs.
