Jay-Z fans were on Tuesday left furious after tickets for the upcoming charity show were snatched by scalpers.

New York-born hip-hop artist and businessman will stage the show at Madison Square Garden on September 11 to mark the eighth anniversary of the September 11 attacks and to aid the New York Police and Fire Fighters Widows' and Children's Benefit Fund, the charity set up to provide for the families of first responders injured or lost during the September 11 terrorists attacks.

CitiBank customers had the opportunity to get pre-sale tickets to the concert titled Answer the Call at 9 a.m. (EST) on Tuesday morning on the Ticketmaster Web site - three hours before going on general sale.

However when fans tried to purchase their tickets at noon online, many were notified there were no seats left - and found tickets priced at $54.50 on sale at highly inflated prices on Ticketmaster's resale Web site, TicketsNow.com, and similar agencies.

Jay-Z's Madison Square Garden date is his only scheduled show in the New York for 2009.
