Senate President Aquilino Pimentel III on Monday signed the arrest order against former Commission on Elections (Comelec) chief Andres Bautista.
Senator Francis Escudero, chairman of the Senate Committee on Banks and Financial Institutions, confirmed Pimentel has signed the arrest order.
The Senate Sergeant at Arms has received the copy of the arrest order and will be sending another copy to Bautista's address.
Bautista is currently out of country.
Earlier this month, Escudero sought the issuance of an arrest warrant against ex-poll chief Andres Bautista after the latter's failure to attend a Senate committee inquiry on his alleged violation of the Anti-Money Laundering Act.
Escudero said the fact that Bautista did not even give a forwarding address is "clearly an attempt to stifle" the proceedings.
Bautista’s wife, Patricia, earlier accused the ex-poll chief of amassing nearly P1-billion in unexplained wealth.
