"Representatives of the Dutch Financial Intelligence and Investigation Service and the Dutch Public Prosecutor recently visited Shell at its headquarters, " a spokesman said.
"The visit was related to OPL 245, an offshore block in Nigeria that was the subject of a series of long-standing disputes with the Federal Government of Nigeria."
Shell is cooperating with the authorities and is looking into the allegations, the spokesman said.
