According to the docs, obtained by TMZ, Patricia claimed she was the real mother of Robert and Yolanda's 2, 14-year-old twins. He says he fears Patricia might kidnap them when she has a delusional episode.
Robert claims, "Patricia kicked me, punched me, threatened to kill me, jumped on me, pulled my hair very hard, pounded my head into the floor ... because I would not divulge where her mother was hiding. The real goal was to do far greater injury to her mother."
He went on ... "She did not explicitly say she would use a weapon but did say she would kill my mother and kill me."
According to the docs, 2 officers took Patricia to a psychiatric ward where she was placed on a 5150 involuntary psychiatric hold. The docs say this is the 2nd or 3rd time she was placed on a psych hold.
The judge granted a temporary restraining order but the matter was dropped after that.
TMZ broke the story earlier today ... just a month before the Delta incident -- where she was arrested after allegedly spitting on and hitting an 80-year-old man on the plane -- she was busted for DUI and tried to fight the cops and EMTs.
