Two other suspects escaped when Omili Police intercepted and proceeded to the location.
Metropolitan Superintendent Anthony Wagambie Jnr said the suspect had been serving time at Buyevi Correctional Services in the Southern Highlands for rape and attempted murder.
Apart from being wanted for rape and attempted murder, the suspect is also wanted for the murder of a high school student two years ago in Lae.
He will be formally arrested and charged after receiving medical treatment at the Angau Memorial Hospital.
