The suspect in the New York-area bombings over the weekend had once worked as an unarmed guard for private security companies, according to documents uncovered by the Associated Press Tuesday evening.

Ahmad Khan Rahami, an Afghan immigrant, had worked as a night guard for the AP’s administration office in Cranbury, New Jersey, in 2011. Danny Spriggs, AP’s chief of global security, said Rahami was known for engaging coworkers in political discussions and expresses empathy for the Taliban. It is unclear whether Rahami’s colleagues had reported him to authorities.
