Several charges have been laid against a southern Alberta man who is accused of using a sex video to try to extort money from his former lover.

RCMP say they got word last month about a man who secretly recorded some intimate moments with an Ontario woman.

Police allege he demanded money from the alleged victim to keep the video private.

On March 8 officers executed a search warrant at the suspect's home in Sundre, which is about 115 kilometres north of Calgary.

The 56-year-old man was charged with extortion, criminal harassment, voyeurism, distributing intimate images without consent and two firearms-related offences. He will appear in court on March 21.
