Hussain al-Kwawahir was being held Monday in Detroit on allegations of using a passport with a missing page and lying to U.S. Customs and Border Protection agents.

Pressure cookers packed with explosive powder and shrapnel were used in the Boston Marathon bombings last month, killing three people and wounding more than 250.

Authorities say al-Kwawahir initially said he brought the cooker with him for his nephew, who he said is a university student in Ohio. He later changed that story and was arrested on suspicion of making a false statement.
