The joint forces arrested 509 people across the country under 'Operation Devil Hunt' on the sixth day of the operation, according to the police headquarters.
This brings the total number of arrests under the operation to 3,924 as of Friday afternoon, it said.
A further 948 arrests were made on the day, which fell outside the purview of Devil Hunt.
During the sixth day's operations, the joint forces also recovered arms and ammunition including one shooter gun, one a barrel gun and some local weapons.
The government launched the nationwide security operation on Saturday night, ostensibly aiming to curb unrest and ensure public safety.
