Members of Saudi Arabia's wealthy Baeshen family, who control one of the Middle East's leading tea purveyors, AMS Baeshen & Co., are suing the reorganized Bahraini private equity and investment firm Arcapita Bank for the return of millions of dollars they'd earmarked for the bank's aborted stock sale. Lawyers for the Baeshens, the family behind the Rabea Tea brand, are seeking the return of some $3.5 million deposited at the bank in connection with the Bahraini bank's abandoned rights offering.
