The French government has been scrambling to contain the fallout from the death of a activist over the weekend in southern France.
Remi Fraisse was killed in an explosion during a violent clash with police in an environmental protest at a dam.
Forensic results are due that will determine whether police were responsible.
The French Interior Minister, Bernard Cazeneuve, said while they are “waiting for the conclusions of the inquiry” he had “asked for the suspension of the use of stun grenades.”
Politicians have come under fire for what has been perceived response to the death.
The incident came after weeks of protests by those opposed to a dam they claim will destroy the environment and will only benefit a small number of farmers.
“Now we know until where they are able to go. And here there are people who are really motivated and we will not let them win,” said one protester.
The prosecutor handling the case has reportedly defended the police. She said they were being mobbed by a violent crowd of demonstrators at the time of Fraisse’s death.
The victim’s family have reportedly made an official complaint alleging murder.
