Several protesters were being arrested outside McDonald's headquarters on Wednesday, as hundreds demonstrated in a bid to call attention to the low pay earned by fast-food workers.

The demonstration comes ahead of the fast-food chain's annual shareholders meeting Thursday, where it is also expected to be confronted on issues including its executive pay packages and marketing to children and minority communities.

Early Wednesday, organizers changed the location of their demonstration after learning that McDonald's closed the building where they had planned their actions. The corporate headquarters in Oak Brook, Illinois has several buildings on a sprawling campus.

Down the street from Hamburger University, police officers warned protesters that they would be arrested if they didn't disperse, and several arrests were made soon after.
