Davor Dragicevic, a father seeking justice for his tragically deceased son, who was detained on Tuesday under the charges of “posing a threat to security” has been released on Wednesday following the interrogation at the District Prosecutor's Office.

“I will be at the (David's) Square at 6 o'clock and I don't plan to leave my child to criminals and murderers,” Dragicevic told reporters following the release. He added he would be “fighting until the end.”

Dragicevic was apprehended for posing “a threat to security,” police said a few days after they initiated a procedure at competent court against Dragicevic and several other persons. They gathered in front of the Republika Srpska (RS) entity institutions on December 17, at the moment when new government of this Serb-dominated Bosnia's part was appointed.

The gathering in front of the institutions violated the Law on Public Peace and Order and the Law on Public Gathering, according to the police.

Dragicevic said he had information a night before that he would be detained on Tuesday.

Tuesday's apprehension of Dragicevic and several opposition politicians sparked a fierce reaction among the crowd who have been supporting the father in his quest for justice for his son who, it turned out, was murdered in March this year.

For months ‘Justice for David’ group has been protesting in Banja Luka's central square demanding from competent authorities to resolve the death of Dragicevic's 21-year-old son, David Dragicevic. The gatherings at the square they named after David turned into the anti-government protest as the father claimed his son was brutally killed and that the Interior Minister, Dragan Lukac, was an accomplice.

On Tuesday, police cleared the memorial to David from the square and removed the protesters, who continued the gathering at a nearby location.

Suzana Radanovic, the young man's mother who was briefly apprehended on Tuesday, said they had information that “Serbian special police unit” was also present in Banja Luka during the Tuesday gathering. She urged Serbia's President to react.

Serbian Internal Affairs Minister Nebojsa Stefanovic denied claims that Serbian police personnel were present during the protest in Banja Luka or anywhere else in the Republika Srpska. “I want to say that everyone who claims that Serbian police personnel were present at the demonstrations in Banja Luka is a liar,” Stefanovic said.

The parents who announced a new peaceful gathering at the central Banja Luka square for Wednesday afternoon claim they have information about “a bloodshed” being planned for that day.

Neither Radanovic nor Dragicevic specified what that meant but only said the citizens should gather in “a peaceful and dignified manner.”

Dragicevic's attorney, Ifet Feraget, told media that his client knew nothing about the summon the police were talking about. 

The power was abused, according to him, and conditions were met for Minister Lukac to resign.
