Eight people linked to extreme-right groups are being questioned in the death this week of a young far-left militant after a fight with skinheads in Paris.

A spokeswoman for the prosecutor's office said that an autopsy was being carried out Friday on the body of 19-year-old Clement Meric, a student at Sciences Po, one of France's most prestigious universities. He died in the hospital after the clash Wednesday between the two extremist groups.

Agnes Thibault-Lecuivre said that a 20-year-old is suspected of dealing what became the fatal blow.

Investigators are trying to establish whether that suspect belongs to the Revolutionary Nationalist Youth group or another organized extreme-right movement.

The deadly brawl has spurred calls for authorities to ban extreme-right groups that have grown more visible in recent months.
