Australian guard held taking snaps up women's skirts

Kok Chuen Chong, 49, used a mobile phone secreted in a shopping bag to record video footage up women's dresses 507 times over a two-year period, Perth Now quoted police as saying Tuesday.

Chong, who was employed by Wilson Security, allegedly committed the offences while working at shopping centres in Perth and its suburbs, as well as at Channel 10's Dianella studios between Oct 3, 2007 and Dec 17, 2009.

Police moved in when a member of the public alerted officers to an incident at a shopping centre in Innalooon, a suburb, Dec 17 last year in which the accused allegedly tried to take inappropriate images of two students.

Detectives have charged Chong with 507 counts of committing an indecent act. It is understood police have seized his mobile phone and computer as evidence.

He will appear in a magistrate court in Perth Sept 3.
