FIVE Liverpool fans were arrested on suspicion of using counterfeit money ahead of last night's first leg of the Champions League knockout round tie against Benfica.
Portuguese police arrested them at the Holiday Inn in Lisbon yesterday morning, spokeswoman Paula Monteiro said.
It is believed the five were arrested after attempting to use counterfeit euros to pay taxi, hotel and bar bills.
The spokeswoman said: "The information we have is that they were here for the game."
The Foreign Office said last night that consular officials were still making inquiries to establish the full facts.
Chief Superintendent Dave Lewis, Merseyside police's liaison officer in Lisbon for the match, said afterwards that the game passed off without major incident.
He added: "Over 3,000 supporters travelled to the game but there were no real issues that caused us any problems. People were well-behaved and police did not have to take any action.
"We had excellent cooperation with the police in Lisbon, and we will look to repay them when they come to Liverpool in two weeks' time."
