Iran has arrested four suspects in the killing of a prosecutor in an attack which a judiciary official said may have been carried out by PJAK militants, Iranian media reported on Tuesday.
Vali Haji Gholizadeh, prosecutor in the northwestern city of Khoy in a region bordering Turkey, was shot dead in front of his home on Monday night.
"So far, no group has claimed responsibility for this terrorist act," provincial judiciary chief Mohammad Ali Mousavi was quoted as saying by ISNA news agency.
"But in view of the threats and plans the PJAK group had announced previously, it is probable that this group is involved in the assassination," he said.
Khoy's governor, Ebrahim Mohammadlou, said four suspects had been arrested in connection with Monday's assassination.
He said the city's prosecutor appeared to have been killed by "hostile anti-revolution groups", the semi-official Mehr News Agency added.
The assassination took place six days after a remote-controlled bomb killed a university scientist in Tehran.
Iranian officials have blamed the United States and Israel for the bombing attack that killed the Tehran University Professor, Massoud Ali-Mohammadi. The United States dismissed the allegation of U.S. involvement.
