Papua New Guinea's attorney general, Ano Pala, has handed himself in to police for questioning.
The Supreme Court this week dismissed an application by Mr Pala to restrain police from enforcing an arrest warrant against him.
He is accused of conspiring with others to defeat the course of justice in relation to the Paraka lawyers scandal, which has engulfed many high-ranking officials, including the prime minister.
He had said he couldn't hand himself in because he was busy at parliament.
Mr Pala walked into the National Fraud and Anti-Corruption Directorate Office in Port Moresby at 10 o'clock this morning.
The assistant Police Commissioner for Crimes, Thomas Eluh, said the minister had voluntarily gone in for questioning by officers.
