Ticketholders for Bill Cosby's upcoming shows in New York have been offered refunds if they no longer want to see the embattled comic perform.

The veteran comedian's sex abuse scandal has dominated headlines in recent weeks and prompted the cancellation of a number of stand-up shows on his current U.S. tour.

Cosby, who has faced historical sexual assault allegations from a number of actresses and models, is due to perform two gigs in Tarrytown, New York on 6 December (14).

The shows are still on, but bosses of the Tarrytown Music Hall venue have now offered ticketholders refunds if they no longer want to attend.

A message posted on the venue's Facebook.com page, reads, "Very pleased to announce that we are now able to offer a full refund to all Dec 6 Cosby ticket holders who no longer wish to attend. Look for an email with instructions. Thank you to all parties involved in negotiating this deal."

The email sent to ticketholders, obtained by local news publication Lohud.com, reads, "Mr. Cosby's management is now allowing for refunds for any patron's (sic) that do not wish to attend the show. Please let me know if I may cancel and refund your order."

Cosby's lawyer has dismissed the sexual assault allegations as false.
