Story highlights Five men who describe themselves in a complaint as "human rights activists of Mexican origin" filed a lawsuit Wednesday against Trump

The lawsuit stems from a physical confrontation between protesters outside a Trump event and a member of Trump's security team

Washington (CNN) After filing a flurry of lawsuits during since the launch of his presidential campaign, Donald Trump is on the receiving end of one after a confrontation in New York last week between a protester and a member of his security detail turned violent.

Five men who describe themselves in a complaint as "human rights activists of Mexican origin" filed a lawsuit Wednesday against the Republican presidential candidate, his campaign, his company and Keith Schiller, Trump's chief of security. The plaintiffs allege that Trump security officials, namely Schiller, assaulted them as they protested outside of a campaign event.

Last Thursday, the five plaintiffs stood outside of Trump Tower where a campaign event was taking place with a sign saying "TRUMP: Make America Racist Again" - a play on the Republican candidate's slogan, "Make America Great Again."
