Former Barcelona President, Sandro Rosell, has been arrested as part of a money-laundering investigation.
According to Spanish newspaper El Confidencial, the arrests are part of a joint operation between the Spanish police and the FBI, related to the United States-led investigation into corruption at FIFA.
A number of other people were also held as police raided nine offices and homes in north-eastern Catalonia.
Rosell was Barcelona president from 2010 to 2014, when he resigned following a Spanish court’s decision to investigate the 2013 signing of Neymar. In June 2016, Barcelona paid a fine of 5.5million euros (£4.7m) over Neymar move from Santos. The club was accused of tax fraud, which it denied.
Rosell’s wife was among those arrested.
