Edmonton police have laid a number of charges against a man, stemming from incidents reported in recent months, and investigators are seeking further information on other possible incidents.

Detectives with the Sexual Assault Section said Dennis Chung, aka Kok Cheun Chung, 50, was facing a total of 14 charges ranging from sexual assault, gang sexual assault, to possession for the purpose of trafficking and breach of recognizance.

The charges stem from three incidents involving two women, who had gone to Chung’s home between May and July 2013.

Police said that it’s alleged in each incident that the women were rendered semi-unconscious, and were sexually assaulted by the accused.

Additional charges against Chung are pending, and anyone with information about the reported incidents or other related incidents is asked to call the Edmonton Police Service non-emergency line at 780-423-4567 or #377 on a mobile phone.
