A businessman who has admitted more than 20 offences of rape, assault and upskirting offences against at least six women may have secretly filmed hundreds of victims.

Chao Xu, 33, preyed on women at his office, at his riverside apartment and in the street, Woolwich crown court heard.

It is feared that he has claimed hundreds more victims in almost five years of depraved offending who have yet to come forward.

Police officers are currently going through thousands of images and content on Xu’s seized devices and believe the scale of his offending could be vast as an appeal was made for potential victims to come forward.

Xu - who is from China and is believed to have lived in the UK since 2013 - denied only two out of the 26 charges he faced at a plea and trial preparation.
