Bartomeu released after appearing before judge: court

The two men, who were arrested on Monday, "exercised their right not to speak", and the judge granted them conditional release while the investigation continues, the Barcelona court said in a statement.

Bartomeu resigned in October, avoiding a vote of no confidence triggered after more than 20,000 club members signed a petition against him.

His departure came in the same month Barcelona announced losses of 97 million euros ($114 million) for last season and following a dramatic decline in performances on the pitch as well as a personal falling-out with Messi.

The operation comes less than a week before presidential elections are to be held at the club.
