In the NCCIA Karachi raid call centre case, the operation allegedly targeted American citizens in a scam worth billions of dollars over more than a year.
The NCCIA arrested 273 people in a raid on a call centre on Shahrah-e-Faisal, Karachi, on Tuesday night.
Officers seized 339 laptops, 152 mobile phones and four CPUs.
Officials allege the centre used credit-card and loan pitches, mostly aimed at retired people, to defraud American citizens.
This time employees were arrested too, not only owners and managers.
The court granted bail to suspects under 18 and to women; other accused were sent to jail on judicial remand.
