Four young Indonesian recruits died as they underwent a tough initiation into the riot police force, including a 13km run. Some witnesses reported seeing blood flowing from their mouths, suggesting they had been beaten. But observers say such tough treatment is not surprising for a police force renowned for its aggressive culture and poor recruitment methods. Police said over a dozen recruits collapsed and four men died after 166 recruits were forced last week to complete a 13km run from the central police headquarters to the Brimob (riot police) headquarters in Palu, central Sulawesi. 'They were rushed to the hospital, but there was not much the doctors could do for these four recruits,' said Brigadier General Taufik Ridha, central Sulawesi's police chief. Apart from the four who died, aged from 20 to 24, another 16 collapsed. Eight recruits were reported to be still recovering in the hospital's emergency ward. National police said they had decided to move the Brimob commander in central Sulawesi, Adjutant Commissioner Herson Bagus Pribadi, to Jakarta. Police denied reporters access to the bodies, which is unusual in Indonesia. But witnesses reported seeing blood flowing from the recruits' mouths, according to reports in The Jakarta Post.
