Update: Melissa Lastman (the CPC candidate) issued a statement last night.

TL:DR her version:

• She said she ended her interview with Menzies when he brought her sexual orientation into it, suggesting she was here due to her sexual orientation, not her merit..
• After speaking to a few more constituents, she then left because she "felt unsafe".
• She says she didn't call the cops and has not spoken to them in relation this incident.
