KARACHI: Investigation teams were astonished to learn about Raymond Davis’s alleged connections in North Waziristan, sources told DawnNews.

Sources have revealed that a GPS chip recovered from Davis was being used in identifying targets for drone attacks in the tribal region.

It was also learnt during the probe that Davis made upto 12 visits to the tribal areas without informing Pakistani officials.

The 36- year-old US official was reluctant in giving out information about his visits to the tribal region, sources added.

The US Embassy officials were exerting pressure on the authorities, asking them not to expose the information received from Davis.

Meanwhile, the Punjab government has shared the investigation and the possessions recovered from Davis with the federal government, said sources.
