There was chaos in the Big Brother Naija house on Monday night after a heated altercation between Tram and Keivo turned violent.

Tram had accused Keivo of stealing a black shirt.

Denying the allegation, Keivo claimed that he owned a similar shirt.

While expressing his frustration at being tagged a thief, Keivo punched Tram.

After attempts by other housemates to separate them failed, the Big Brother voice instructed all the housemates to freeze as he deployed three ninjas to contain the situation.
