Free tickets for Bon Jovi's summer concert in New York have been selling for as much as $1000 on eBay, it's been revealed.

Tickets for the concert in Central Park had originally been given to fans for free but a number have since appeared on the online auction website.

Speaking to the New York Post, a spokesperson for the event said: "It's very disappointing in the spirit of a free concert that individuals would try to take advantage."

It's understood that organisers are considering imposing a ban on anyone who buys a ticket to the concert on the black market.

The 60,000 capacity concert will take place on July 12th.
