BRASILIA, Feb 3 (Reuters) - Brazil's federal police have

opened an investigation into potential fraudulent ‌management at

state-run lender BRB, two sources ​familiar with the

matter told Reuters ‍on Tuesday.

The probe ⁠deepens scrutiny ⁠of BRB following its failed

attempt to ‌acquire Banco Master, ​a deal blocked by the central

bank in September.

The ⁠central bank ‍later ​ordered Master's liquidation in

November amid a liquidity crisis, and BRB ‍executives were

removed from their posts.

In a statement on Tuesday, BRB said it had submitted a

preliminary audit report ​with "relevant ‍findings" to the federal

police and the central bank.

The lender ​added that it has taken a range of institutional,

administrative, extrajudicial and legal measures to protect its

interests, recover credits and assets, ​and seek compensation for

losses.
