Steve-O cancels comedy shows after Ryan Dunn death

Steve-O has cancelled several upcoming stand-up comedy performances in the wake of Jackass co-star Ryan Dunn's death.

Dunn was killed Monday after he crashed his Porsche in West Goshen Township, PA. His good friend Zachary Hartwell, a passenger in Dunn's car, died as a result of injuries sustained in the accident.

The Jackass star was more than double the legal blood-alcohol limit at the time of the crash.

Steve-O, who mourned Dunn in a Twitter post on Monday, has now called off a slate of comedy gigs at Sacramento's Punch Line venue which were to take place over the next week.

A statement on the venue's website read: "These performances have been postponed, to be rescheduled for a later date. Refunds are available at place of purchase."

Steve-O's decision to refrain from public appearances in the immediate future comes two days after his fellow Jackass stars Johnny Knoxville and Bam Margera gathered with Dunn's friends and family at a private memorial service in Westchester, PA.

Dunn was 34 years old at the time of his death.
