A guard at the arms factory in Grams, 50 miles south of the capital Tirana, noticed a person inside the facility without permission taking pictures, a ministry spokesman said. Guards arrested the person, but in the process were injured by a “neo-paralytic spray,” the statement said, possibly referring to pepper spray. The suspect was identified as a 24-year-old Russian national with the initials M Z. Another Russian woman, S.T., 33, and a Ukrainian man, F.A., 25, were arrested outside the complex and their vehicle was confiscated. “Three people were being escorted by the police who in cooperation with other institutions are investigating the case,” the statement said, adding that the military police, army intelligence police and civil and counter-terrorism police were coordinating the case.
