Woman mugged on Brazil TV while discussing crime

Brazilian TV is showing footage of a woman being robbed while being interviewed on television about crime near Rio de Janeiro's main train station.
The images of the interview conducted yesterday by TV Globo were posted on its G1 Internet news portal.
The woman is complaining in the clip about the lack of police presence near the station when the would-be mugger approaches her from behind and rips off what appears to be a gold necklace.
The clip shows the thief fleeing down a busy street, and the reporter is seen chasing him for a few seconds. The thief, however, was left empty handed. He dropped the necklace, which was returned to the woman.
