A French policeman who was shot during yesterday's terror attack has died of his injuries.
The 45-year-old swapped himself with a female hostage in a supermarket in southern France - before the gunman was killed.
He left his mobile on so officers outside knew what was happening.
Prosecutor Francois Molins described him as a hero after the attack.
Anti-terror police have made a second arrest in connection with their investigation.
A 17-year-old suspect who knew the attacker has been detained.
A woman he knew was held yesterday.
