Serb lawmakers are discussing security in their mini-state in Bosnia after the suspicious death of a student triggered daily protests and cover-up accusations against top police officials.

David Dragicevic, 21, disappeared in March and was found dead a week later, his body dumped in a river in Banja Luka, the biggest town in Republika Srpska.

Police initially said Dragicevic had killed himself after taking drugs and robbing a house, which outraged his father, Davor Dragicevic, who insists his son was murdered.

The father's "Justice for David" movement has organized more than a month of daily protests, in a challenge to the government of pro-Russian President Milorad Dodik.

Davor Dragicevic, speaking at a special session in parliament Thursday, accused top police officials of covering up the crime, which they denied. He did not say what he thought motivated the alleged cover-up.
