Peter O'Kane, a Winnipeg police officer who was at the centre of a perjury trial last year, has died.

Police confirmed that O'Kane died in hospital on Wednesday.

The boxer-turned-officer had fallen down some stairs at a friend's house on Saturday night, and his condition worsened in hospital.

O'Kane made headlines in recent years, after he and Const. Jess Zebrun were accused of perjury in connection to a drug arrest.

The officers were accused of giving misleading or false statements under oath at a 2006 preliminary inquiry of two men accused of drug trafficking. The case fell apart when the perjury allegations came to light.

The case against the officers was tossed in February 2011, after the Crown failed to prove their identities to a jury.

In September, the Manitoba Court of Appeal ordered a new trial for both officers.
