Rohinie Bisesar admitted to the crime through an email she sent to The National Post just before her arrest. “I am sorry about the incidence. I felt the need to be extreme to see if it would work. I would normally not do such a thing,” Bisesar wrote.

The woman also asked in her email: “Do you know any top professionals in artificial intelligence, biotechnology, nanotechnology, satellites? Maybe Military. Maybe Government?”
