Fans of Benedict Cumberbatch are outraged after learning he will not be attending a Sherlock convention.
People had paid up to €3495 (£3000) for the VIP tickets, which grants direct access to the show's stars at the Sherlocked convention in London.
The three-day event at the ExCel centre in London runs from 23 September and fans are annoyed the show's main stars - Benedict and Martin Freeman, who plays Doctor Watson - will not be attending, according to The Telegraph.
The line-up was announced on Thursday, and will include Mark Gatiss, who writes, produces and stars in the show as Sherlock's brother Mycroft, Andrew Scott who plays villain Moriarty, and Amanda Abbington, who is Martin Freeman's on and off-screen wife.
Cumberbatch's parents, actors Timothy Carlton and Wanda Ventham, who played Sherlock and Mycroft's parents in the detective series, will also be attending the convention.
A spokeswoman for Cumberbatch told Mail Online the actor was on holiday with his wife Sophie Hunter and their young son Christopher.
Fans who paid $3495 (£2,999) for the top tickets voiced their grievances online after it was announced the show's main stars would not be attending.
"Why on earth did I buy a Gold ticket?" wrote one, while another posted, "I am going to try and get my refund off Sherlocked if I die doing it. I see no reason why they should get to keep my money."
However, organisers of the event stated that no refunds would be given to disgruntled fans.
TV drama Sherlock attracted 8.4 million viewers, the highest overnight audience of the festive season across all channels with the exception of the New Year's Eve fireworks on BBC One, which was watched by more than 12 million, the BBC said.
