The suspect, who was shot dead by French police, was the subject of a "Fiche S" surveillance file and was on the radar of the French domestic security service DGSI, the source said.
The man was a French national who shot two officers in 2001 after being stopped by a police car, the source said. He was taken into custody but while being questioned grabbed another officer's gun and shot him three times, the source said. He was convicted in that attack and had a criminal record because of involvement in violent robberies, the source said.
