Prominent Lawyer Paul Paraka has been slapped with 18 counts, in relation to payments made by the State to his law firm.
Port Moresby-based Task Force Unit, arrested Paraka at Kupiano in Central province, at dawn today.
He was picked up whilst there to buy timber.
Paraka was brought in around 11 o' clock to the National Anti Corruption Fraud Squad office at Konedobu and questioned for more than four hours.
He was then taken to Boroko Police Station where he was formally charged and locked up.
National Capital District Metropolitan Superintendent Andy Bawa, confirmed late this afternoon, Paraka was refused bail.
Paraka's lawyers are working on his bail application however, NBC News understands they will have to follow the formal court process to apply for this.
His case relates to millions of Kina paid by the State to his law firm between 2011 and 2012, whilst two Supreme Court Orders prevented such.
Mr Paraka has maintained his innocence and says he will fight to clear his name.
