Three former board members of Spanish second division club Osasuna have been arrested in an investigation into the destination of 2.4 million euros ($A3.4m) taken from the club's accounts, a court source confirmed on Thursday.

"This morning ex-president Miguel Archanco and former directors Angel Vizcay and Jesus Maria Peralta have been arrested," said a statement from the Navarran High Court of Justice.

All three are expected to have an initial hearing in front of a judge on Friday.

The court in Pamplona will also investigate a complaint made by the Spanish Professional League for misappropriation of funds and corruption in match-fixing allegations.

Last month the current Osasuna board announced that just over 2.4 million euros from the club's accounts couldn't be accounted for.

Archanco was in charge of the Navarran club from 2012 to 2014, but resigned after Osasuna were relegated last May after a 14-year stay in the top flight.

Spanish sports daily Marca reported last month that Spanish league officials were investigating four matches involving Osasuna towards the end of last season for alleged match-fixing.
