Brazilian team joins London shooting probe

The killing of Jean Charles de Menezes, 27, in a London underground train as police hunted for men who a day earlier had left bombs that failed to explode on three trains and a bus has prompted calls for London police chief Ian Blair to resign.

"We are here to see how the investigation works," Marcio Pereira Pinto Garcia of the Ministry of Justice told reporters as he and Wagner Goncalves of the Federal Prosecutor's Office arrived at London's Heathrow airport from Brazil.
