Police were called to controversial ex-baseball player Jose Canseco's Las Vegas home over the weekend (22-23Nov14) after his fiancee accused him of threatening her life.

Cops responded to an emergency call placed by Leila Knight late on Saturday (22Nov14) and investigated the domestic incident, which reportedly occurred after she called off her engagement to Canseco.

She told officers the former sportsman had "threatened to kill me and my mother" and had repeated the words "like, 20 times" after revealing she was leaving him.

Canseco and Knight were questioned but no arrests were made after cops decided instead to issue warnings to both parties.

The baseball star has denied threatening Knight and insists she is simply bitter after he broke up with her.

He tells Tmz.com, "She's slandering me because I don't want to be with her... I fell out of love with her because she's too controlling."

The couple became engaged in 2013.

News of the domestic incident emerges a month after Canseco was hospitalised after accidentally shooting himself in the finger while cleaning his gun.
