Keith Beams, from Croydon, is due to appear at Thames magistrates court on 13 April charged with two counts of common assault and one count of criminal damage, a Metropolitan police spokesperson said.
The enforcement officer was arrested on 30 January shortly after bailiffs and police moved to evict the Occupy movement's educational hub, the so-called Bank of Ideas, from a disused office in the City of London.
About 50 activists were evicted peacefully, but protesters claimed tensions had risen during a subsequent eviction when police and bailiffs moved to clear a squat unrelated to Occupy but located in the same UBS-owned office complex.
One of the people who Beams, 45, is alleged to have assaulted was a photographer, Jules Mattsson, whose camera was allegedly damaged.
