Prime Minister Zoran Zaev on Tuesday held a meeting with the heads of the institutions in charge of investigating the escape of former secret police chief Sasho Mijalkov.

Zaev, the government said in a press release, arranged the meeting to be briefed on all aspects of recent events, as well as on the ongoing investigation and steps that institutions need to take.

“The Prime Minister stands firmly behind his position that all relevant institutions have the responsibility to locate Sasho Mijalkov. The PM has said that citizens are expecting an explanations and that institutions are obliged to answer all questions regarding the case, stressing that compromise over justice and responsibility is impossible,” the press release read.

The Ministry of Interior has issued an international arrest warrant for ex-secret police chief Sasho Mijalkov, who as of Sunday afternoon has not been available to law enforcement officials.

The incident has caused public reactions, with demands being made for taking responsibility and opening an investigation into possible errors on account of relevant institutions.

On Sunday, the police failed to find Mijalkov and give the house arrest order, which was submitted to the Skopje Criminal Court by the prosecution.

The order was filed due to the danger of escape pending the trial verdict in the “Target-Fortress” case on Feb. 26, in which Mijalkov is one of the defendants. The prosecutors, who delivered the closing arguments at the previous hearing in the case, demanded maximum prison sentence for Mijalkov.

According to the indictment, between 2008 and 2015, defendants in the “Target-Fortress” case by using three different surveillance systems for intercepting communications as part of the former secret police, illegally wiretapped close to 4,300 telephone numbers without obtaining court orders to do so.
