Former Barcelona president Sandro Rosell has been arrested as part of a money-laundering investigation.

A number of other people were also held as police raided nine offices and homes in north-eastern Catalonia.

The arrests are part of an investigation into rights sales relating to Brazil, police sources say.

Rosell was Barca president from 2010 to 2014, when he resigned following a Spanish court’s decision to investigate the 2013 signing of Brazilian Neymar.
