According to border guards, the man is a persona non grata in the country.
"The incident did take place. The man is now at Lavoriškės border checkpoint. But the reason is that he is on Lithuania's persona non grata list. The border guard who checked his documents through databases saw this information, but neither the institution that put him on the list nor when it was done," Giedrius Misutis, head of the Public Relations Board, told BNS.
Asked whether the Belarusian citizen had a Lithuanian visa, Misutis said: "The documents were in order but the fact that he was on the database was a signal for the border guard that this man cannot be allowed in."
In his words, similar situations take place "always daily, and these people are returned to their country once all documents are taken care of."
Meanwhile the Ministry of Foreign Affairs refused to comment.
"Based on the usual international practice, the Ministry of Foreign Affairs does not comment on cases when persons are not allowed in or refused visas," the ministry told BNS.
Ulasevich is introduced on the Seimas website as a coordinator of civil campaign "Ostrovets Nuclear Power Plant Is a Crime."
Lithuanian MP Kazimieras Uoka told BNS he went to Lavoriškės border checkpoint to express his "resentment over such a decision by state institutions." He said he would try to ensure Ulasevich's remote participation in the discussion with the help of communication technologies.
"Ulasevich ran for the Belarusian parliament but later stepped down in protest together with other opposition representatives. It might be a mistake or the hand of the Belarusian KGB," Uoka wondered why the Belarusian activist was not allowed into the country.
