The Minister of Internal Affairs Ivan Demerdzhiev

Ivan Demerdzhiev is a lawyer with over 20 years of experience.

He was born in 1975 in Plovdiv.

In 2001, he commented on bomb threats to dozens of schools in the country, which are still being sent today.

Yesterday, schools in Sofia, Varna and Burgas also received threats of planted explosive devices via e-mail.

"What is happening to us at the moment is also happening in many other European countries. We are working on the signals and I hope within days we will have a result on who is sending these signals and from what origin they are," said the interior minister.

He added that at this stage this is speculation, the threats are coming from a Google account and there is no way to determine the source.

It is because of this that the American services are currently working, because "Google" is theirs.

Assumptions vary, but it is most likely an attack originating from Russia.

"Don't worry, nothing will happen on the election day, if it happens we will assess how real the threat is and whether there will be a reason to interrupt the election day," he added.

"At the moment there are actions all over the country, I told you that there will be, expect in the coming days even more arrests and even greater inspections," warned Demerdzhiev.
