The Associated Press reports that, as of early Tuesday, about 100 people have been arrested following the breakup of a protest by Denver police.
The confrontation erupted Monday night as police in riot gear tried to disperse a crowd of about 300 people that was disrupting traffic near the Denver City and County Building.
Police said they were forced to use pepper spray when members of the crowd, some carrying rocks, rushed a police safety line. But one protester said officers charged the protesters with no warning.
Those arrested faced charges for violating city ordinances including failure to obey a lawful order, obstructing a public roadway and interference.
"The bonds have ben set low enough so that we believe that most people will bond out in a relatively short time," said John Harrison of the Joint Information Center, a command set up by city, state and federal authorities to field media inquiries during the convention.
Harrison said two officers deployed pepper spray during the incident, while another officer shot pepper balls, similar to a paint ball containing pepper spray.
The American News Project has video of the protest, and the ensuing violence.
