Ivan Naskevich said that the investigation is considering four versions of what happened, tut.by reports.
"The most obvious, and it is already confirmed, is the version that the pyrotechnic charges were probably of improper quality. Now there is a different question: they were originally of improper quality or have become such - it is the most pressing issue for investigation," - RIA Novosti quotes the head of the Investigative Committee.
Naskevich also confirmed that the preventive measure in the form of imprisonment was chosen for the Russians detained in the case. The charges will be brought against them within the 10-day period established by law.
