COPENHAGEN, Denmark (AP) — The headquarters of one of Sweden's largest banks are being raided by authorities as part of an investigation into whether Swedbank was connected to a massive money laundering scandal in the Baltic countries.

Sweden's Economic Crime Authority says Wednesday's search was done on behalf of chief prosecutor Thomas Langrot, who is probing whether 15 of Swedbank's largest shareholders illegally received information about the bank's connection to the money laundering scandal before a Swedish television report on the issue last month.

Broadcaster SVT had reported that Swedbank customers had been able to funnel at least 40 billion kronor ($4.3 billion) between Swedbank and Danske Bank in Estonia.

Estonia has ordered Danske Bank to shut its local subsidiary after the bank admitted massive amounts of money had been laundered.
