"#Urgent A gendarmerie operation underway at Lardin Saint Lazare. Local residents are asked to stay at home," the prefect tweeted on Sunday morning.

The police were called to resolve a family dispute on Saturday night when a woman's ex-partner came to her home with a gun and attacked her new partner.

The woman's ex-partner, who is a former military, then shot at the police, damaging two vehicles before running away.
