On 19 January, one day before the police raided Dotcom's home, a police officer visited the multi-million dollar mansion to learn about the property. Security-conscious Dotcom wanted the police to understand how to get around the property if he alerted the police to a threat, Davison said.
The police officer hid a camera inside a pen, he said, and captured images from inside the home.
Davison alleges the police knew that Dotcom had four children and another on the way when his home was raided by 76 police officers.
"The police officer on the 19th was told [Dotcom's] wife was pregnant and due to give birth," Davison said.
