Denver (AP) Denver authorities are busy morning processing about 100 people who were arrested when police officers and protesters clashed about a mile from the site of the Democratic National Convention.
The confrontation erupted last 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 say they were forced to use pepper spray when members of the crowd, some carrying rocks, rushed a police safety line. But some protesters say officers charged them with no warning.
Those arrested faced carges for violating city ordinances including failure to obey a lawful order, obstructing a public roadway and interference.
It's believed to be the first time a police-protester confrontation turned physical and the first time officers used any kind of chemical spray since demonstrations began on Sunday.
