Gang link suspected in unprovoked 'punch-and-runs' on Sixth Street

It doesn't get into whether people were being slapped in the back of the neck, but maybe there's a connection.

Austin police said they have received at least eight reports this year in which Sixth Street revelers were punched in the head or mouth, unprovoked, while standing on the sidewalk or walking down the street. The attackers fled.
