French authorities arrested two more suspects on Wednesday. They are investigating the fatal beating of 23-year-old Quentin Deranque, a far-right activist.

Deranque was beaten last week on the sidelines of a protest in Lyon, France. At least six people attacked him.

A total of 11 suspects have been arrested. An assistant to a hard-left parliament member is among those arrested. The killing has heightened political tensions before municipal elections next month.
