Paris, Apr. 11 : French president Nicolas Sarkozy has received a letter containing two bullets, prompting speculation that one was intended for him and the other for his wife, Carla Bruni.

It is the second time in a month the president has been sent death threats by post, but the first time France''s First Lady has potentially been targeted.

The menacing package, which was addressed to Sarkozy, was delivered to the Elysée palace on Thursday, the Scotsman reports.

The two 9mm rounds were sent with a threatening letter posted in southern France the day before. It was intercepted by security before it reached the president''s office. Elysée palace officials did not reveal the contents of the letter, but said an investigation had been launched to discover who sent it.

The Parisian prosecutor''s office, which is handling the investigation, said the package was similar to previous ones received in recent weeks by Mr Sarkozy, justice minister Rachida Dati and other members of the French government.

Last month, police arrested and released without charge a man on suspicion of sending Sarkozy and several of his ministers envelopes, each containing a 9mm cartridge. (ANI)
