The apprehended terrorists have admitted to their crimes during police investigations, he said.
Abbaszadeh did not elaborate which group the detained individuals belonged to.
The group, he said, played a role in instigating violent riots in Ahvaz during protests against fuel price hikes in November.
The November protests descended into violence after riotous elements — some of them armed — infiltrated the protests, perpetrating acts of vandalism against public and private property, according to witnesses and official reports.
In some cases, reports indicated that certain elements had randomly shot at individuals present in the vicinity of protest locations in a bid to provoke further violence and unrest.
Iranian officials have said the attempts were backed by certain foreign states.
