A new autopsy has claimed that the Cameroonian footballer Albert Ebossé was stabbed and brutally beaten to death in the changing rooms after a match in Algeria and not an object thrown by rioting fans as had been initially claimed.

A Cameroonian pathologist believes that the 24-year-old, who played for the Algerian Ligue 1 side JS Kabylie, was killed as the result of “brutal aggression” amid “signs of a struggle” in the changing room after the game in August.

The official report had stated Ebossé had “succumbed to a head injury after being hit in the head at the end of the meeting with USM Alger”, which the home side lost 2-1. The incident led to JS Kabylie club being banned from African competitions for two years, and forced to play home league matches behind closed doors.

However, AFP reported that the Cameroonian pathologist Dr André Moune had alleged Ebossé had suffered upper body injuries and received “a blow to the head” that caused “an indentation of the skull” after the game on 23 August. He also claimed that there was evidence of a “rupture of his cervical vertebrae” and a collarbone wound “that we believe must have been caused by a knife”.

Moune’s findings have been sent to Algerian and Cameroonian authorities for further action, while Ebossé’s family said they have asked the Confederation of African Football to investigate further.

According to AFP, the family also claimed at a press conference held on Saturday that neither JS Kabylie or the Algerian league had provided financial compensation as promised.
