How do you know it is Humberside police and you're not just spreading fake news there? Could well be another force AFAIK the officers haven't been identified (could possibly be staged even) and the whole thing is out of context.
Humberside Police have said it's not their officers. The provenance of this video is a bit curious too, it seems to have first started doing the rounds courtesy of an American journalist who failed to do any research and erroneously linked it to Humberside.
Fascinating insight into Communist systems.
