Brian Stelter, reporting in the New York Times (emphasis mine):
"Ms. Christ said that police officers took a New York Post reporter standing near her and 'threw him in a choke-hold.'
That reporter and two photographers with him declined to speak on the record because they are freelance workers and lack some of the job protections of full-time employees. But as they sipped coffee on Tuesday morning in Foley Square, where some of the protesters had regrouped, they expressed surprise at the extent of what they described as police suppression of the press.
There's certainly an argument to be made about freedom of the press here, and that's the main point of the article.
There's another argument to be made here, too, and I think it's even more important - about the erosion of rights and the relationship between employers and employees in general.
