Seven players representing Football League clubs have been arrested in connection with alleged bribery and money laundering.
The National Crime Agency have announced that the players in question are from clubs based in the North-West of England.
The authorities have also confirmed that six people have been re-arrested, meaning that 13 individuals in total are being questioned by police up and down the country.
The players, aged from 18 to 30, have been held as part of an investigation into alleged illegal activity within football.
The news comes as part of the authorities' second investigation into match-fixing when six people were originally taken into custody in December regarding claims that a Championship match was fixed.
