Five people were arrested Friday afternoon outside a Burlingame, CA hotel where Donald Trump was giving a speech. At least one Trump supporter, who walked through a crowd of protesters, was punched (more on that below). CNN reports on the scene outside the hotel:

Protesters — some of whom wore bandanas over their faces and carried Mexican flags — blocked off the road in front of the Hyatt Regency here, forcing the GOP front-runner’s motorcade to pull over along a concrete median outside the hotel’s back entrance. Trump and his entourage got out and walked into the building.

“That was not the easiest entrance I’ve ever made,” Trump said once he began speaking at the convention, adding, “it felt like I was crossing the border.”

At one point before Trump arrived, about two dozen protesters tried to rush barriers near the hotel. Police officers then rushed to the building’s doors, successfully blocking the protesters from getting in. Some of the doors’ handles were handcuffed from the inside so they couldn’t be forced open.

Several physical altercations, including shoving, could be seen between protesters and police officers, who were using batons to push them back.

Images of the confrontation with police were posted on Twitter. As you can see, Mexican flags were flying:

There were chants including “F— the GOP”:

Some of the protesters did make it inside the Hyatt hotel where Trump was speaking:

Some protesters were beating up a Trump pinata:

Pretty sure the guy who finally took down the Trump pinata is dressed as Captain Mexico. [Note: another NSFW chant in this clip]

And the requisite burning of the American flag:

A man named Chris Conway walked through a group of protesters shouting “Trump!” while wearing a red Trump cap. That led to a scuffle and one protester in a black hoodie and mask struck Conway in the back of the head. Conway also claimed others were kicking him. The protesters are clearly close to losing it with one saying Conway is lucky to get away. And it seems he is lucky that the police finally pull him to the side of the road and protect him from the angry mob until he can climb over a bush and escape. This raw footage of the incident was shot by KTVU:

Here’s another angle showing Conway getting punched in the head:
