Rio police teams exchanged gunfire in Jacarepaguá, Brazil, early on Sunday 11 October, killing an elite BOPE officer and wounding five others after officers mistook colleagues for criminals, according to the state military police.
BOPE officers had been stopping a car when colleagues from the 18th Military Police Battalion encountered them on a dark street. The force's account, reported by G1 and O Globo, described battalion officers mistaking the stop for a crime and opening fire.
