Brazil police probing alleged mob killing in Rio's tony Ipanema neighborhood

Rio de Janeiro police say they are investigating the apparent mob killing of a 33-year-old ice vendor in the heart of the Olympic city's Ipanema neighborhood.

The police said in an emailed statement Monday that they've spoken to witnesses and requested surveillance videos to help shed light on the circumstances of Fabiano Machado da Silva's death on Sunday.

Rio's O Globo daily newspaper reported that a crowd of around 10 people chased Silva through the expensive and exclusive beachside neighborhood. The report said the mob caught him at a central square and pummeled him with punches and kicks.

The paper quoted a police investigator as saying that passers-by later joined in on the beating.

It was not immediately clear what motivated the slaying.
