CALGARY - A Calgary man accused of filming women without their knowledge and posting their images to a Twitter account called "Canada Creep" is facing additional charges.

Jeffrey Robert Williamson, 42, was freed on bail on Thursday after being charged with three counts each of voyeurism and publication of voyeuristic recordings in relation to three alleged incidents.

But Calgary police say he was rearrested on Friday and charged Saturday with possession of child pornography and accessing child pornography.

Investigators say they seized a number of electronic devices that contained multiple terabytes of data, including alleged child pornography.

Police allege Williamson had been posting photos and videos -- some shot up the skirts of unsuspecting women -- and say the investigation is ongoing.

He is scheduled to appear in court on Monday.
