I don't know who they were referring to in the report, although you could probably contact them to inquire about the specifics.
But just by quickly searching Google I found quite a few instances in which real reporters were harmed or arrested: A WNYW Fox photographer (Roy Isen) was maced/attacked with a baton, a Milwaukee Journal Sentinel photographer (Kristyna Wentz-Graff) was arrested despite her credentials hanging from her neck, an RT television reporter (Lucy Kafanov) was struck with a baton, a journalist in TN (Jonathan Meador) was arrested. John Farley (a reporter for WNET in NY) was arrested. That's just from 5 minutes of searching, so it wouldn't surprise me if the 25 figure only represented professionals.
