Spanish prosecutors are demanding a 15-year sentence for a man who is accused of strangling his mother and eating her remains.

Known as the "cannibal of Ventas" after the Madrid district where police discovered the flat containing the remains, the suspect went on trial this week charged with murder and desecrating a body.

According to the indictment, the incident occurred in early 2019 when the suspect had a row with his 69-year-old mother at the flat they shared.

It is alleged that he strangled his mother and dismembered her remains before eating some of them.

The indictment said he stored other parts in various plastic containers around the house and put some in the bin.

The suspect was arrested on 23 February 2019 after police turned up to make inquiries about his mother who had been reported missing by a friend, local media reports said at the time.

Asked at the door if his mother was inside, he said she was, and let them in.

"We found a hellish scene," an unidentified police officer told Telecinco news channel, with police saying the suspect was known for having drug issues.

Prosecutors are seeking a 15-year jail term and have called for him to pay €90,000 in compensation to his older brother.
