On a tip-off, the Golra police raided a house located in E-11 and found the couple shackled in the basement.
They were identified as Shazia Bibi and Tariq Ali, natives of Chinniot.
The police later arrested the employer and her son.
The police said the couple had been working in the house for the last three months during which the employer did not pay them the salary.
The two arrested persons were produced in a court from where they were shifted to Adiala Jail on a judicial remand.
