Among those arrested last night at a Ferguson, Missouri, protest was St. Louis Alderman Antonio French, for unlawful assembly. Using Twitter and Vine, French has been reporting on the unrest that has followed the police killing of Michael Brown, a black, unarmed 18-year-old who was walking down the street. From USA Today:

French, alderman of the 21st ward in St. Louis, was taken into custody, said his wife, Jasenka Benac French, who uses the Twitter handle @senka.

She tweeted that "@antonioFrench is in Ferguson jail," and that he had been arrested. About 90 minutes later she tweeted, "@AntonioFrench being booked now. Not sure what the charge is yet. Was ordered out of his car and arrested because he "didn’t listen.’"

French was released at around 7 a.m. CDT according to a tweet from journalist Gabe Bullard.
