St. Louis Alderman Antonio French was arrested Wednesday night after publishing tweets showing the unrest in a Missouri suburb where an unarmed black teenager was shot and killed by police officers over the weekend.

The arrest was confirmed by French’s wife on Twitter.

French’s detention triggered outrage on social media, with individuals demanding his immediate release, tweeting under the hashtag “#FreeAntonio.”

Others headed to the jailhouse where they gathered outside.

A spokesperson for the Ferguson County Jail was not immediately available for comment to TheBlaze. It was not clear at the time of publication what French was charged with.

The alderman has been tweeting Vine videos for past several nights documenting the unrest in Ferguson, Missouri.

Earlier Wednesday, two reporters said they were assaulted and arrested by police officers for not exiting a McDonald’s fast enough.
