In a press release here, the TRS leader said hundreds of Indian prisoners are lodged in jails in the Gulf nation.
The unemployed youth going to Saudi Arabia for jobs are exploited by their employers, who do not pay wages for several months, he said.
Out of desperation, they are forced to find other employment, without documentation, which often leads to their arrest, Kumar said.
He appealed to Swaraj to direct Indian embassy in Riyadh to ensure immediate release of such prisoners.
