The Taseer family had been receiving threats since the killing of the former governor in January this year at the hands of his own security guard, Mumtaz Qadri, of the Elite Force who was opposed to Taseer's opinion that the country's blasphemy laws needed to be amended.
Confessing to his crime, Qadri had said he had killed Taseer for "committing blasphemy".
The anti-terrorism court hearing the case, adjourned the proceedings today till September 10.
Taseer had requested President Asif Ali Zardari to suspend the death sentence of a Christian woman, Asia Bibi, in a blasphemy case.
Religious extremist groups, who said Qadri had done a "commendable job to kill a blasphemer," had warned the court and the government against convicting him.
Punjab Governor Sardar Latif Khosa has accused Shahbaz Sharif's Punjab government of "having indirect link with the kidnapping of Taseer junior".
A 'Qadri's Lovers Group' has been active in holding demonstrations and issuing warnings to the government.
"We had taken two Afghans into custody yesterday night from Gulberg but later released as they were only present there," Hamid said.
ASP Hamid said police had taken the finger print record on the car of Taseer and sent it to the National Database Registration Authority for identification of the kidnappers.
"We have also got the telephone record of Shahbaz," he said.
Meanwhile, Punjab Governor Khosa accused the Punjab governor of being indirectly responsible for Taseer's kidnapping.
Referring to the Sharifs he said: "Earlier they had killed Salman Taseer and now they have kidnapped his son".
The governor said he would ask the PPP co-chairman Zardari to review its reconciliation policy with the PML-N as the PPP could not tolerate "more accesses of the PML-N government".
