From a Baltimore CBS affiliate:

BALTIMORE (WJZ)– Caught on camera– a tourist being beaten in downtown Baltimore and instead of helping him, a crowd laughs and steals his belongings.

Mike Hellgren has the video and the investigation.

Police hope this video will get the attackers off the streets.

The video shows a man being punched in the face in Downtown Baltimore. You can hear his head hit the pavement near the entrance to Courthouse East.

Instead of helping, people laugh.

Then, the crowd strips him naked and takes his car keys, watch, money and iPhone.
