Police have urged Lincoln City fans to not resell their tickets for the sold-out FA Cup replay against Championship side Ipswich Town.
More than 8,000 seats for the Imps fans section of the ground have been sold with the last tickets being taken on Thursday afternoon.
Supporters were able to buy up to 10 tickets at a time, and many who missed out despite queueing have been angered to see tickets being resold at a profit.
The LincolnshireLive news website reported that the county’s police took to social media to warn ticket holders that reselling for financial gain is “unethical” and could lead to action.
The force said: “We have had reports of people selling tickets for profit on social media.
“Lincoln is a small community, this is not only unethical but could land the individuals in trouble, please think about your actions. Respect your fellow supporters and DO NOT RELIST/SELL for financial gain.”
The average number of general sale tickets purchased was approximately four per transaction, according to the club. However, many fans complained via social media that the club should have limited purchases to just two per transaction.
Speaking to BBC Radio Lincolnshire, managing director Kevin Cooke responded: “[Restricting ticket purchases] would have meant more people queuing. When we checked the data, despite the fact that you could buy 10 tickets, most people on average bought four.”
Lincoln had to suspend online sales of FA Cup tickets earlier this week after an influx of fans became too much for the club’s website to handle.
