SAO PAULO, Nov 27 (Reuters) - Independent board members at Brazilian investment bank BTG Pactual SA are reviewing the facts related to allegations against controlling shareholder André Esteves, interim chief executive Persio Arida said in a letter obtained by Reuters on Friday.
In the letter, Arida reaffirmed that "the bank is solid and in a position of financial strength," allaying fears of accelerating withdrawals after Esteves was arrested Wednesday on suspicion of obstructing a vast corruption investigation.
