Security officials have said that police have detained a man suspected of attempting to drive his vehicle into soldiers who were out jogging near their military barracks in Varces-Allieres-Et-Riset in the French Alps.
In the original incident, a man shouted death threats from his car window at several groups of French soldiers out for a morning jog in the French Alps before trying to run two of them over, a military spokesman said.
Colonel Benoit Brulot, a French Army spokesman, told the AP that the driver circled the military barracks in Varces-Allieres-et-Risset, in the south-eastern Isere region, shouting at groups of soldiers.
He returned later and tried to hit the two soldiers with his car before making a quick getaway.
Mr Brulot said that none of the soldiers, from the 27th Mountain Infantry Brigade, was injured.
