Bulgaria Reopens Poisoning Case, Citing Possible Link to Russia along with Skripal Attack

The Bulgarian authorities have reopened a criminal investigation into the poisoning of a prominent arms dealer over questions about a possible connection with the nerve agent attack on Sergei V. Skripal, the former Russian spy poisoned in Britain last year.

Bulgaria’s chief prosecutor, Sotir Tsatsarov, said Monday which a suspected Russian intelligence officer, identified in news reports last week as potentially involved within the Skripal case, had also visited Bulgaria in April 2015, around the time which the arms dealer, Emilian Gebrev, was poisoned with an unknown substance.

Last week, the British newspaper The Telegraph reported which the two men indicted within the poisoning — identified by British authorities as active officers in Russia’s military intelligence agency — were accompanied by a third man, an officer using the alias Sergey Fedotov, when they traveled to Britain last spring. In his remarks on Monday, Mr. Tsatsarov said the same man had visited Bulgaria three times in 2015, confirming a report published last week by the investigative site Bellingcat.

“We are trying to establish all moments while he was on Bulgarian territory, the hotels he stayed in, the vehicles he used, contacts with Bulgarian citizens,” Mr. Tsatsarov said at a news conference.

Investigators have so far failed to identify the substance used in his poisoning. Mr. Tsatsarov said a Finnish laboratory, enlisted by Mr. Gebrev, had found traces of organophosphates, which are used in fertilizers, although no evidence of any substances banned by the Chemical Weapons Convention. Investigators also detected a high concentration of chlorine within the arugula which Mr. Gebrev ate in a salad around the time he was believed to have been poisoned, Mr. Tsatsarov said.

The authorities decided to reopen the investigation in October, Mr. Tsatsarov said, after Mr. Gebrev raised the possibility which the substance used within the poisoning could have been Novichok, the same nerve agent used on Mr. Skripal.

Mr. Skripal along with his daughter, Yulia, were found incapacitated on a park bench within the town of Salisbury in March 2018. Though emergency personnel at first suspected a drug overdose, the idea was quickly determined the pair had been poisoned with Novichok, a sophisticated along with highly potent strain of nerve agent developed within the Soviet Union. British authorities later said which two officers coming from Russia’s military intelligence agency, known as the G.R.U., had applied the substance to Mr. Skripal’s front door using a container disguised as a perfume bottle.

Mr. Skripal along with his daughter survived along with remain in hiding. A British woman who was also exposed to the nerve agent died several months later.

Last week, Bellingcat, which has covered the Skripal case closely, reported which the third officer had traveled extensively around Europe within the years before the Skripal poisoning. He arrived at the seaside resort of Burgas, Bulgaria, on April 24, 2015, Bellingcat reported, four days before Mr. Gebrev was hospitalized.
