'You're all dead men walking': The sinister threat sent with a BULLET to French politicians including Sarkozy

Death threats and bullets have been sent to a number of French politicians, including President Nicolas Sarkozy.

Justice Minister Rachida Dati and Interior Minister Michele Alliot-Marie have also received the brown envelopes containing a 9mm cartridge and an identical letter in the past two weeks, a source said.

The note included threats such as 'you are all dead men walking' and 'your lives and your families' lives are in our hands'.

Anti-terrorist specialists from the Paris prosecutors' office have been put in charge of investigating the threats.

There was no comment from Sarkozy's office or any of the ministers' offices.

The latest person to receive one of the letters was former Prime Minister Alain Juppe, now mayor of Bordeaux in the southwest.

'I'm not worried. It is up to the police to analyse the evidence and take necessary measures,'  Juppe said.

Among other threats, the letters say: 'You think you have control of your lives, well no, your lives and your families' lives are in our hands.'

It was not clear whether the author was making any specific demand or defending any stated cause.

Bordeaux chief prosecutor Claude Laplaud told reporters there was no clear lead so far.

He said investigators were considering the possibility that the letters could be the work of a mentally unstable person.

Juppe said he had lodged a formal complaint to the police because it was normal procedure to do so, but was not asking for extra protection.

'I am not going to change my plans. If you start reading anonymous letters when you're in politics, you'll never finish,' he said.
