French policing called into question again after brutal arrest at peaceful march

A brutal arrest during a peaceful march against police violence has again put French law and order under the spotlight, as the government, fearing further unrest, banned fireworks outside authorised displays during the Bastille Day holiday weekend.

Amid continuing tensions after rioting sparked by last month's fatal shooting of a teenager, police faced further accusations of brutality on Sunday when video emerged of the arrest of the brother of a black man who died in custody seven years ago.
