Columbus Short -- My Wife's Under Police Scrutiny Too

The woman who caught a beating at the hands of Columbus Short's estranged wife now wants to press criminal charges ... TMZ has learned.

As TMZ first reported, Short's wife, Tanee McCall, went BALLISTIC and attacked Short's friend, Tilly Key, back in February when Key showed up at Short's house to help him move out. For some reason, Short recorded the whole thing.

Now law enforcement sources tell TMZ ... Key showed up at the Lost Hills Sheriff Station Thursday and filed a battery report against McCall. We're told police will interview Columbus and Tanee.

We're told Key has been getting a lot of random phone calls lately and noticed lots of random accounts on Twitter have started following her. She panicked, and filed the police report.

Key even got into it with McCall this week online ... after McCall favorited a tweet of Key's, to which Key responded, "Stay away from me... I have 2 years to press charges. You already told me 'I'm gonna slit your throat, I'm gonna kill you, gonna break your neck' that's enough already."
