"The plans to install surveillance cameras are currently being discussed, all financial and technical options are analyzed," the municipality's Public Relations Division said in a reply to BNS about plans to build cameras at Pilsudski's grave.
Last Saturday, the police received a report that a poster saying "Tomaševski Stop Doing Damage to Lithuania Or Your Place Will Be Here" was found near the grave, and later on, a carton box was also found with inscriptions "Poles Will Die", "Call the Cops", "Careful, Bomb" and "TNT".
Valdemar Tomaševski is the leader of the Electoral Action of Poles in Lithuania, a party that is currently partaking in the ruling majority.
On Monday, the Union of Poles of Lithuania has expressed resentment over the incident.
"The Supreme Board of the Union of Poles of Lithuania is outraged over reoccurring hooligan acts denigrating the memory of the deceased at a location which has special importance for the Poles," the Union said in a statement on Monday.
Pilsudski is credited for his contribution to the restoration of Poland's independence after World War One. But in Lithuania Pilsudski is often referred to negatively for his involvement in the occupation of Vilnius region. His body is buried in Krakow, while his heart is in Vilnius.
