Bakotic led the break of 1,249 inmates on 22 April 1945, the Park's Council recalled in a statement, adding that more than 83,000 innocent people were killed at Jasenovac, including more than 20,000 children.
The Park's Council expects the police and other state bodies to find and punish "the perpetrator of this terrible anti-democratic and anti-Croatian act."
An unknown perpetrator on Saturday night tried to remove Bakotic's memorial plaque from the house where he was born in Sinj, damaging it in the process.
The act was condemned by the War Veterans Ministry and the Sinj mayor as well.
