With another Russian spying case settled this week, authorities warn there may be more to come in the future.
"It would be naïve to think that, if there have been four convictions in the last few years, then that's that. The previous director general of KaPo said after the Aleksei Dressen case that it would certainly not be the last. I fear that nor will Veitman be the last," Arnold Sinisalu, head of the Estonian counterintelligence agency KaPo, told Eesti Päevaleht.
Asked in an interview to scale up the damage done by three Estonians now in prison for treason, Sinisalu said Herman Simm likely caused the most harm for the government while Dressen and Veitman caused problems for KaPo as an agency.
Speaking at a press conference on Wednesday, Sinisalu had said: "Nikolai Ermakov [Veitman's recruiter] did not deal only with Vladimir Veitman and we know of more than one individual who has been in contact with Nikolai Jermakov for the purpose of collecting intelligence. We highly recommend that the people who have been in contact with Nikolai Jermakov, or if this person used a different name, turn to KaPo."
A former KaPo official, Vladamir Veitman was sentenced to 15 years in prison for treason this week. He was arrested in August after having retired from the agency in 2011. The files relating to his case will not be disclosed for 50 years.
