Nick Gordon, late Bobbi Kristina'sboy friendis now being accused of injecting her with a fatal “toxic mixture,” that eventually led to her death on July 26, new court documents revealed on Friday.

According to the document, which is in response to Gordon’s legal team’s efforts to stay the ongoing wrongful death lawsuit filed by Brown’s conservatorBedelia Hargrove, “Ms. Brown died due to a violent altercation with Defendant (Gordon) after which he placed her in a bathtub, unconscious, after he injected her with a toxic mixture."

A Radar online report indicated that, the lawsuit, which was amended after brown’s deathand seeks $10 million in damages, accuses Gordon of givingBobby Brownand the late Whitney Houston’s daughter a “toxic cocktail rendering her unconscious.” There was no mention of an injection.

Kristina died on July 26 at the age of 22 after being placed in a medically induced comma for nearly six months after she was found facedown and unconscious in a bathtub full of water in her home on Jan. 31.

Hargrove’s case also accuses Gordon of verbally and physically abusing [his girlfriend, as well as withdrawing funds from her accounts after her hospitalization.

The new documents note that “Bobbi Kristina Brown was physically abused by the Defendant on numerous occasions and later died following a particularly violent altercation with the Defendant which left her battered and bruised, with a tooth knocked out,” and that she was ultimately “fatally injured” at their shared Atlanta home.

Gordon’s lawyers have denied the claims of the alleged toxic cocktail and that he abused and stole from her.
