Peru's former Minister Enrique Cornejo turned himself to the national police on Wednesday.
They had been included in the probe on alleged bribes paid by Brazilian construction company Odebrecht to former Government officials.
Cornejo told reporters he had not been involved in bribe payments made during Alan Garcia's second term in office (2006-2011).
He served as Minister of Transport-Communications (2008-2011) and Housing-Construction-Sanitation (2007-2008) under the Garcia administration.
