The failed Times Square car bombing suspect is believed to have been working alone, according to media reports Wednesday.

Authorities indicated that Faisal Shahzad, the 30-year-old son of a retired air force official in Pakistan, had launched the bomb plot alone almost immediately after returning to his Connecticut home in February from the visit to his native land.

Authorities don't believe there are any other suspects in the plot and that several arrests in Pakistan in the past two days were not related.

Police said that two new surveillance videos emerged of the bomb suspect, Faisal Shahzad, according to reports Wednesday.

One video shows him in a white baseball cap and a dark jacket walking away from the smoking, bomb-laden Nissan Pathfinder parked in the bustling heart of New York City.

The second video shows him buying a weak batch of fireworks in a store in Pennsylvania, according to the shop's owner.

According to former reports, Shahzad has waived his right to a speedy arraignment, a sign indicating he is willing to provide more valuable intelligence, adding that no court appearance has been scheduled.

Shahzad was arrested as he was trying to flee the country in a Dubai-bound jet late Monday.

He faces terrorism and weapons charges after authorities said he admitted rigging the Pathfinder with a crude bomb of firecrackers, propane and alarm clocks based on explosives training he received in Pakistan.
