The families of some Muslim youth, detained in connection with the twin blasts, on Tuesday alleged police harassment in the name of investigations and threatened to launch an agitation if they were not released immediately.
The city-based civil rights activists claimed that over 40 youths had been picked up since the August 25 blasts that claimed 43 lives but none of them was produced in the court.
The family members, who included daily wage earners, told reporters here that their dear ones were picked up by plainclothes policemen without giving any reasons and their fate was not known.
"My younger son was taken away by police from my house on Thursday. As a precaution I had sent my elder son with him. Both of them have not returned so far. Please return my sons," Mujeebunnisa, an elderly widow, said.
Zaheda Begum, mother of Rayees Ahmad, said her son was taken away by two policemen in civil dress, when he was returning home from work in Secunderabad area.
He has already faced a lot of harassment at the hands of the police since the blast in Mecca Masjid. He lost his earlier job and his engagement was broken because of the police action, she said. Ghousia Begum, mother of auto driver Abdul Raheem, said her son was dragged from home by the police Monday night. He is the sole bread earner of the family.
"I am a heart patient and I do not have the money even for my medicine. Where should we go for justice," she asked.
