Juan Carlos Monzon Rojas, the alleged leader of a customs corruption scandal that has rocked the Guatemalan government, has turned himself into authorities.

A Guatemala judge has set a hearing for Monzon early Monday.

Monzon, the personal secretary of former Vice President Roxana Baldetti, is accused by authorities of being the head of corruption ring in which businesses allegedly paid kickbacks to government officials in exchange for lower import duties. It is believed that the scheme bilked the government of millions of dollars.

The scandal so far has caused former President Otto Perez Molina and Baldetti to resign. Both are jailed and are facing charges for allegedly receiving the illegal payments.
