I’d better shut up then! I don't understand how this will solve anything as far as th Maifia are concerned The book is now published and of course the Mafia has just given the best publicity anyone could give by doing what they have done. I for one hadn't heard of the book before this story came out proving my point. Mafia inteligence? I don't think so!
The centre-right cabinet is under pressure at home and from the European Union to deliver on its pledge to tame powerful organised crime gangs and punish corrupt officials.
Bobi Tsankov was killed in central Sofia in broad daylight, Interior Minister Tsvetan Tsvetanov told Focus news agency. Two other men at the site of the shooting were wounded and rushed to hospital, police said.
There have been more than 150 gangland assassinations since 2001. But despite its campaigns against crime and graft, Bulgaria has failed to show results which may lead to sanctions from Brussels, which cut millions of euros in aid in 2008.
Bulgaria has sent to jail only one crime boss since communism collapsed in 1989 and has so far failed to convict a single senior official of graft.
But the new government of Prime Minister Boiko Borisov has taken a harder line since coming to power.
Last month police struck a rare blow against organised crime by arresting more than 25 suspected kidnappers whose abductions of the rich and famous have blackened the new EU member's image.
Tsankov, 30, had publicly revealed his connections with alleged crime bosses and had published a book on the Bulgarian underworld. In 2006, he was injured by a bomb outside his home.
Last November, he told police he had received death threats shortly before his book's publication, local media reported.
Two years ago, Georgi Stoev, the author of a series of books on the emergence of Bulgaria's underworld in the 1990s, was gunned down in front of a hotel in central Sofia.
