Woman Calls Cops On Cops?

What in tarnation was going on in this Sacramento, California apartment? See if you can figure it out. From The Sacramento Bee:

Police attempted to serve a warrant on Fairfield Avenue. 
Officers said that they 
heard a woman talking inside the apartment, and they 
knocked, identified 
themselves as police officers and asked to speak to the 
woman. A man inside 
replied that she wasn’t there, but they could come back 
later. Officers again heard 
a woman inside and re-identified themselves, adding that 
if the occupants did 
not open the door, it would be forced open. After the 
residents again refused to 
open the door, it was forced open, and the woman was 
found talking to police 
and reporting that someone was trying to break into her 
apartment.

Uh… Sorry, wrong number.
