The deputy chief of the Human Trafficking Combating Center, Iurie Podarilov, detained last week, is likely to remain behind bars.
The prosecutors are going to ask the court for a warrant of 30 days in custody for him.
Podarilov is suspected that he and one of his subalterns asked for EUR30,000 to terminate a criminal case. They received the first installment of EUR10,000.
Prosecutors say they discovered evidence to back their claims, following searches.
The suspects face up to 15 years of jail and fines of about $25,000.
