SAN FRANCISCO – Twitter on Monday began to shed its name and logo – both online and in the real world – but not before city police questioned whether crews were cleared to dismantle the iconic signage that has long graced its headquarters in San Francisco.

The signage removal work was paused while San Francisco police checked to see if a permit was in place to close the street. Unlike the signature blue bird, everything was on the up and up, and no tickets or citations were issued, police said in an email to the Bay Area News Group.
