U.S. authorities accuse Faisal Shahzad of driving a car bomb into New York's Times Square on Saturday with the intention of killing as many people as possible in one of the busiest places in the country.
Here are some facts about him:
* Shahzad was born in June 1979 to a family hailing from Pabbi, northwest of the Pakistani capital Islamabad. He recently visited Pakistan for about five months, returning to the United States in February, prosecutors said.
* He first came to the United States in 1998 on a student visa, according to the Daily Telegraph in London.
* He first attended Southeastern University in Washington, D.C., but later transferred to Bridgeport University in Connecticut. He graduated with a degree in computer science and engineering, and later attained an MBA, the Telegraph reported.
* Shahzad became a naturalized U.S. citizen last year, U.S. officials said.
* U.S. prosecutors said Shahzad admitted training in Waziristan in northwest Pakistan, a Taliban and al Qaeda stronghold. But an intelligence official in Pakistan said Shahzad received militant training in the nearby town of Kohat. The area around Kohat is a stronghold of Tariq Afridi, the main Pakistani Taliban commander in the region.
* Shahzad is married to Huma Mian, an American citizen, and they have two children, sources said. Mian and the children are believed to be living in Pakistan. The Telegraph reported that neighbors say the family was quiet and wore traditional Muslim dress.
* According to his CV, he enjoys working on computers, playing sports and to "talk to people from different backgrounds", the Telegraph reported.
* Shahzad worked for about three years as a junior financial analyst in the Norwalk, Connecticut, office of the Affinion Group, a marketing and consulting business, the company said. He left the company in June 2009.
* He also worked for an employment agency that supplied accountants and in an unknown role at Elizabeth Arden, the cosmetics company, in 2001, according to the Telegraph.
* JPMorgan Chase's mortgage unit sued Shahzad in September last year to foreclose on his three-bedroom home in Shelton, Connecticut, court documents and county records show. He and his family lived there for almost three years.
* His father, Bahar-ul-Haq, is a retired vice marshal in the Pakistani Air Force, and his uncle, retired Major General Tajul Haq, served as the Inspector General of the Frontier Corps.
