India's acting High Commissioner Manpreet Vohra was called to the foreign ministry, where the Director General (South Asia) handed over a document "seeking further clarifications (and) evidence from the government of India," said a statement from the Foreign Office spokesman.
The clarifications and evidence are needed for "the ongoing investigations in Pakistan relating to the Mumbai terror attacks," it said.
"The information being sought from India is in the spirit of co-operation with Indian authorities and with a view to enabling the relevant authorities in Pakistan to proceed further in the matter," the statement said.
The statement said Pakistan had also requested replies to some queries it had raised earlier and to which India had not yet responded. It did not give details about these queries. Pakistan said it was hopeful that "Indian authorities will provide the information requested as soon as possible".
Earlier in the day, Interior Ministry chief Rehman Malik said Pakistan wanted more information from India, including Mumbai attacker Ajmal Amir Kasab's statement to a judge, for the "successful prosecution" of suspects arrested by it.
Malik said he had told acting High Commissioner Vohra about the information needed by Pakistan to prosecute suspects.
"This information is very important for the successful prosecution (of suspects arrested by Pakistan)," Malik said.
Besides Kasab's statement to a judicial magistrate, Pakistan wants the chargesheet filed against him, details of mobile phone SIM cards and coordinates of GPS equipment used by terrorists involved in the Mumbai attacks and information on any Indian nationals arrested in connection with the incident.
India has blamed Pakistan-based elements, including the Lashker-e-Tayiba, for the Mumbai attacks. New Delhi has linked the resumption of the composite dialogue to Islamabad demonstrating its sincerity to prosecute those responsible for the attacks.
