US billionaire John J Fisher has bought a stake in Celtic, it emerged last night.
The San Francisco-based businessman acquired 3.24% of all shares in Celtic plc, and it is unclear whether he has plans to increase that holding.
According to reports, 46-year-old Fisher had been seeking a British football club in which to make an investment.
The son of GAP clothing empire founder Donald Fisher, John J Fisher is already a co-owner of the Major League baseball team the Oakland Athletics.
The Fisher family had previously been involved with another baseball side, the San Francisco Giants.
According to the Forbes business magazine, Fisher is America's 317th wealthiest man with around $1.5billion (£756million), however he has managed to keep a low profile and whether he has a previous connection with Celtic is unknown.
He is believed to have a strong football interest, however, and has been linked with a move to start up a Major League Soccer side in San Francisco's Bay Area.
Fisher has invested in Celtic through his company Atlas LLC, a California limited liability company.
Meanwhile, Celtic must fend off competition from Borussia Dortmund and Wolfsburg if they want to land German defender Andreas Hinkel next month.
The Germany international is wanted by both Bundesliga sides.
Sevilla sporting director Ramon 'Monchi' Rodriguez said: 'Borussia Dortmund have, along with Wolfsburg, shown concrete interest in Andreas Hinkel.'
Hinkel, 25, is reported to be available for a fee of around £2.1million.
Celtic face managerless Hibernian in the Clydesdale Bank Premier League tomorrow, looking to extend their two-point advantage over Rangers who currently have two games in hand and play Aberdeen on Sunday.
