A 17-year-old female, arrested on Sunday by detectives investigating the circumstances of a man’s death, is “to be reported to the PPS for withholding information”.
The teenager was released from custody on Monday night, and a 35-year-old woman who was also being held over the discovery in Portadown has been released on police bail pending further enquiries.
Three men, two aged 28 and one aged 30, remain in custody.
The PSNI had said earlier that they had been granted an additional 36 hours to question them.
A post mortem is expected to be carried out on the man on Tuesday.
His body was found in a stream off Mourneview Street in the Co Armagh town at around 11am on Sunday.
