RFE/RL contacted the Bulgarian Embassy in London for confirmation, but it said it had no information at the moment and had not been contacted by British authorities. The BBC named the suspects as Orlin Rusev, 45, Biser Djambazov, 41, and Katrin Ivanova, 31. The A spokeswoman for the Bulgarian Foreign Ministry said the department is still investigating the case.
