The employee of Muslim Commercial Bank, Gujranwala district branch, some 80 kilometres from here, told an an Anti-Terrorism Court in Islamabad that accused Shahid Jameel had made a transaction of Rs 15 lakh.
Sources said the prosecution established that Jameel used the money for terror activity. The defence lawyer, however, dismissed the claim.
The court summoned more witnesses for the next hearing on February 26.
The trial is taking place at a slow pace but the prosecution team is upbeat about the case.
Pakistan has acknowledged that the conspiracy behind the attacks was hatched on its soil. India last year handed over five key documents running into nearly 600 pages for use in the trial here so that prosecutors can proceed against the seven accused.
The documents include a certified copy of the Indian Supreme Court's judgement on the case, depositions by two doctors who conducted the autopsy of nine slain terrorists and the chief investigating officer who probed the case.
