Sofia News Agency - The chief of the "Archives and Secret Files" division in the National Intelligence Service was found dead in his office, but the news on his death emerged a day later.

The body of Bozhidar Doychev was discovered Wednesday evening in his office after his family went to his workplace to look for him.

London-based website Kafene.net broke the news first, quoting unnamed EC sources. According to preliminary information, Doychev has committed suicide.

Chief Prosecutor Boris Velchev was alerted of the suicide right after the body was discovered, and he had the military prosecutors launch an investigation into the matter.

So far there is no information on whether Doychev left a suicide note, but some of his colleagues have told Darik News that his desperate act was triggered by personal problems.

Others claim, however, that Doychev may have tried to cover-up some of the information in the classified files, because according to the EC sources, Bulgaria was supposed to start unsealing some of them.

Neither the Interior Ministry, nor the Sofia police have confirmed the information. The chief of the National Intelligence Service Kircho Kirov has not accepted any calls from Bulgarian media to comment on the case.

The National Intelligence Service is one of the special services under the commandment of Bulgarian President Georgi Parvanov. The presidential office has not released any statement on the sudden death of the man who has worked closest to the former communist-time secret files for the last 25 years.
