A court document shows that Canadian businessman and billionaire Frank Stronach is accused of sexually assaulting three different complainants.

The document, which outlines the charges against the 91-year-old, says the alleged incidents took place in 1980, 1986 and last year.

Last week, police said Mr Stronach had been charged with one count of rape, one count of indecent assault of a woman, one count of false imprisonment and two counts of sexual assault , but she gave few details about the allegations.

Criminal defense attorney Brian Greenspan said he was representing Mr. Stronach and that his client “categorically denies the allegations of impropriety that have been made against him.”

Mr. Stronach is the founder and former CEO of auto parts manufacturing giant Magna International. A company spokesman said last week that Mr. Stronach relinquished control of the company more than a decade ago and was no longer affiliated with it.

Police said Stronach was released on conditions and is scheduled to appear at the Brampton, Ont., courthouse on July 8.
