A man allegedly threatened to slit his wife and son’s throats before boarding a train, journalist Jean-Baptise Marty reported. 

When he arrived at Montparnasse, police “subdued” him, Mr Marty added.

He wrote on X: “Completely locked-down sector at station #montparnasse: a man who threatened to slit the throats of his son and his wife at their home boarded a train connecting Rennes to Paris.

“Upon arriving at Gare Montparnasse, he was subdued by police officers. The suspect, armed with a knife, was hit by several bullets from the officers.”
