PPP MPA Sania Naz, was interrogated by Rangers about her suspected ties with gangsters in Lyari, according to reports.
She was called to the Rangers headquarters, where she was questioned for a couple of hours in the light of interrogation with Uzair Baloch.
Naz recorded her statement and was allowed to go home. The Rangers had announced the arrest of Uzair Baloch in January and a day later they informed an anti-terrorism court of his 90-day preventive detention. Later they called former home minister Dr Zulfikar Mirza and recorded his statement.
They also summoned a former president of PPP-Karachi division, Abdul Qadir Patel, to appear before them and record his statement.
Mr Patel, a former member of the National Assembly, reportedly conveyed to the paramilitary force through his lawyer that he was in the United Kingdom for his medical treatment and would return home on March 29.
