Bulgarian exiles in Los Angeles and Paris reported that they had been the victims of attacks resembling the poisoned-umbrella assault that is believed to have caused the death of a Bulgarian defector in London Monday.

Stefan Bankov, who records religious programs for broadcast to Bulgaria, said in Los Angeles that his right side was paralyzed for 10 days after a woman dropped some liquid on his shoulders during a plane trip in 1974.

Vladimir Kostov, a Bulgarian journalist who defected to France, said that he had suffered a high fever and swelling after being struck in the back by a sharp object that pierced his skin while he was leaving the subway in Paris.

Kostov said he was a friend of Georgi Markov, 49, the defector who died in London after telling his family and friends that a man had stabbed him in the leg with the tip of an umbrella.

Radio Free Europe, which broadcast Markov's commentaries to Bulgaria, denied statements by Markov's wife that Markov had been making vitrolic personal attacks on Bulgarian officials and exposing their private lives.

"Mr. Markov's broadcasts over RFE were not vitriolic and never dealt with the private lives of Bulgarian leaders," the anti-Communist agency said.

A court in Cologne, West Germany, freed Croatian extremist leader Stefan Bilandzic after the West German government decided that it would not extradite him and two other Croatians wanted in Yugoslavia for prosecution as terrorists.

Meanwhile, in Wiesbaden, West Germany, the federal criminal office announced the arrest of Leila Bocook, 25, an American teacher described as having connections with the Baader-Meinhof terrorist gang. She was charged with illegal possession of firearms.
