The Pakistani-American man suspected in Saturday's attempted car bombing in New York's Times Square has told authorities he was upset over U.S. drone attacks in Pakistan, especially a drone attack while he was in the country, a U.S. official told Fox News.

The new information about a possible motive in the failed attack comes as Pakistani officials tell Fox News that the suspect, Faisal Shahzad, was introduced to Qari Hussain, the No.3 in the top tier leadership of the Pakistani Taliban on his last trip to Pakistan. U.S. officials couldn't immediately confirm that.

Pakistani officials said they obtained their information after arresting a man in Karachi who is believed to be a friend of the 30-year-old Pakistani-American who allegedly tried to set off a car bomb in Times Square Saturday night. The friend also confessed to having played a crucial role introducing Shahzad to Hussain, a master homicide bomber trainer in North Waziristan where he learned the art of bomb making.

In addition, Shahzad's father-in-law has been arrested and is believed to be a naturalized American Citizen.

Shahzad, however, is believed to have worked alone in the United States on the plot almost immediately after returning from a five-month visit to his native land, authorities said.

Two new surveillance videos emerged of the accused bomber, Faisal Shahzad. Police told The Associated Press that one video shows him in a white baseball cap walking away from the smoking, bomb-laden Nissan Pathfinder parked in the bustling heart of New York City.

Shahzad comes from a wealthy and educated family, and their neighbors in a town, north west of Pakistan say his family is well respected with no connections to militants.

Pakistan's Interior Minister Rehman Malik says there may have been a U.S. facilitator for Shahzad and the 13 trips he made to Pakistan were mostly to Islamabad and Peshawar.

Family members including his elder brother in Canada have been identified along with bank accounts, associates, and cell phone numbers, while some people are being monitored according to on going investigation.
