Three teenage girls who admitted manslaughter after a 75-year-old man died in a street attack that was filmed on a mobile phone have been detained. The girls, who were aged 14, 16 and 17 at the time of the attack, pushed, shoved, kicked and punched Fredi Rivero near a bus stop in Islington, north London, on 27 February, with one of them filming the assault on her phone and grabbing his glasses.
