On April 23, the USA had approached India for Ramachandra Rao's arrest.
"Yes, today we received the red corner notice and the Crime Investigation Department (CID) is examining it," Andhra Pradesh Director General of Police B Prasada Rao told PTI.
Asked about the next course of action, the AP Police chief said "The notice has to be combined with a warrant. The CBI should get the warrant".
In a letter sent by the American National Crime Bureau through Interpol to CBI, the US authorities had said Rao should be put under "provisional arrest" until all the documents were handed over to India through diplomatic channels for his possible extradition to the USA to stand trial in Chicago.
CBI had then sent the letter to Andhra Pradesh police asking them to take action against Rao.
