Police in Brazil have arrested a 17-year-old on suspicion of stabbing his older brother to death after an argument about whether to have burgers or popcorn.

According to the Military Police, the teenager was at the family home in Sorriso, Mato Grosso State, with his brother, Rodrigo Maniezo Fernandes, on 12th May.

That night, a petty quarrel reportedly broke out between the hungry lads about what food they were going to eat.

According to the police, the teenager – whose name is being withheld – wanted to make a hamburger, while Rodrigo, 20, fancied popcorn.

The argument soon took a sinister turn when the younger brother allegedly grabbed a large knife from the kitchen and stabbed Rodrigo in the chest.

According to reports, the wounded sibling ran out into the street and collapsed in a pool of his own blood.

The Fire Department was called, but firefighters could only pronounce him dead at the scene.

The teenager was arrested and taken to the police station, where he was questioned. The alleged murder weapon was also seized.

Rodrigo’s funeral was held on 13th May and he was buried later that day. He had only celebrated turning 20 days earlier, on 7th May, according to local media.

The Civil Police are reportedly investigating the case.
