assault doesnt necessarily mean that she was beaten or hit. you can assault someone without causing any physical harm to them, so the man could have just been violent towards nicki in his speech and actions etc, which scared her, so she called the police.
not saying thats what happened, but it could have. people always assume someone got a beatdown when someones assaulted, which isnt always the case.

son't get me wrong, she could have been beaten, but we will never know that until we see her. and if we dont see her face for a while, then that will defo be suspicious.

and TMZ?! Theyre not CNN, why does everyone believe every word they say. And im not saying that the police lie, but given whats going on in this country, i wouldnt be too surprised, if they found a few corrupt police officers to do something for them
