A heavily armed man has given himself up to police and released two hostages unharmed after holding them in a post office just west of Paris.

French police have said he was an “unbalanced” individual and not a terrorist.

Police said the gunman telephoned them from the post office during the siege. He said that he was protesting against the break-up of a relationship with a girlfriend. He was already known to police as an “unbalanced individual”.
