Denmark's Danske Bank will be investigated in the US over its $230bn Estonian money-laundering scandal.

The company said on Thursday it had “received requests for information from the US Department of Justice (DOJ) in connection with a criminal investigation relating to the bank’s Estonian branch”.

The scandal has already caused the resignation of CEO Thomas Borgen.

Many of the non-resident accounts at the Estonian branch were held by entities or individuals in Russia, which is the subject of US sanctions, Reuters reported.
