The demonstration started at about 4 p.m. outside Quicken Loans Arena where the RNC is being held, and quickly escalated.
Cleveland police posted on social media, saying orders to disperse were ignored:

Here's video showing tension between protesters and police:
When protesters continued to disobey police orders, officers used pepper spray on the crowd and then jumped in to regain order. Several people were handcuffed and taken away.

The protest made it difficult for some delegates to get inside the arena. Police officers told delegates to line up on a yellow line in the street and ordered all others to leave the area.

Police yelled to people to move back as the flag burning group locked arms.
Police wearing riot helmets arrived at the scene and police horses were being used to create a path to a van for people being detained.
Cleveland firefighters were able to put the fire out quickly:
