San Francisco Chronicle, July 16, 2012
Police held 226 mostly minors for questioning Monday after what appeared to be one of Mexico’s first instances of flash mob violence. Ninety-one youths were let go during the day for lack of evidence, while the others remained in custody.
The use of social networks is growing in Mexico, but the country had largely escaped the kind of rapidly formed, fast-moving youth mobs seen in Europe and the United States before the outbreak of violence in the capital Sunday.
[Mexico City police chief Manuel] Mondragon said as many as 600 angry youths who couldn’t get in to the [reggaeton music] concert went on a rampage at local subway stations, damaging turnstiles and streetlamps, robbing people and tossing fireworks in an area popular among foreign residents and tourists. A police car had its windshield smashed.
