AN EVIL couple have been arrested after they beat their nephew, four, so badly he bled from his ears, before burning his body and leaving it to rot in a fridge.

The pair, known as Arturo N. and Karina Guadalupe, had originally told police that he'd been abducted by three kidnappers before the victim's brother revealed what had really happened.

The boy had gone missing in Morelos, Mexico, last year and his body was found decomposing in the fridge.

According to local media, the boy's mother, identified as I.S.Q., left her two sons, five and four years old respectively, with her sister and her partner before he was reproted missing.

The victim's five-year-old brother told his grandmother that his uncle beat the child and made him bleed from his ears and mouth.

He said that the couple burned the victim's body fire in the courtyard.

The grandmother reported the brother's account to the police and the couple were both arrested.

They were charged, but reportedly refused to tell the authorities where the boy's body was.

Investigators discovered that the couple had asked to borrow a fridge from a neighbour because they were moving house.

According to reports, police checked the locked fridge and found the decomposing body inside.

The young victim's remains were sent for an autopsy and the police are still waiting for the results.

Meanwhile, the other children are receiving psychological treatment and are being cared for by social services.

The investigation is ongoing.
