The trouble began when Tram accused Keivo of stealing a black shirt.

Keivo denied taking the shirt, explaining that he owned a similar one. He also voiced frustration at the situation, insisting he refused to be tagged “a thief”.

The two housemates went back and forth until tensions boiled over, with Keivo landing the first punch, sparking a brawl between the pair.

Fellow housemates rushed to pull them apart and calm things down, but their efforts failed as tempers continued to rise.

Biggie, the unseen, authoritative voice that runs the Big Brother Naija house, later stepped in, ordering all housemates to freeze after which he then deployed three ninjas to contain the situation.

This year’s winner stands to claim a record-breaking grand prize of N160 million, the largest payout in the reality show’s history since its debut in 2006.

Of the 24 housemates introduced on July 26, 12 have been evicted, Neche took a voluntary exit, and Nomy was disqualified.

The show is expected to come to a close on October 4.
