The police of the Lviv region of Ukraine on Tuesday detained five people suspected of actively facilitating the violation of the Polish-Ukrainian border and identified six possible organizers of disturbances near the Shehyni checkpoint on September 10.

"In investigating criminal cases dealing with the events that took place at the Shehyni checkpoint at the Ukrainian-Polish border on September 10, the Lviv police on September 12 detained five active participants in those events [...] Law enforcement also determined the identities of six possible organizers of public order violations near the state border and 32 active participants in those events," the Ukrainian Interior Ministry communications department said in a statement on Tuesday.

Over 100 people have been questioned as witnesses, and some parliamentarians have been summoned to undergo investigative procedures, the statement said.

At the present time, the investigation has classified the events at the Shehyni checkpoint under four articles of the Ukrainian Criminal Code: namely, illegal transfer of people across the Ukrainian border, resistance to law enforcement officials in the line of duty, threats or violence toward a law enforcement official, and collective violation of public order.

The Ukrainian State Border Guard Service has also drawn up 15 administrative reports under the Ukrainian Code of Administrative Offences article concerning illegally crossing or attempting to illegally cross the Ukrainian border. Among the individuals against whom administrative offence reports have been compiled are four members of the press and ten foreigners.

Former Georgian President Mikheil Saakashvili arrived in Ukraine on September 10. His supporters gathered at the Shehyni checkpoint and began a fight with border guards in the transit zone, helping Saakashvili and a group of other people, including five parliamentarians, illegally cross the border. Eleven Ukrainian National Police officers and five border guards were injured in the incident.
