Hosam Maher Husein Smadi (born 1990) is a citizen of Jordan who was arrested on suspicion of planning a terrorist bombing of Fountain Place, a building in Dallas, Texas, on September 24, 2009.[1][2][3]

Smadi was in the United States illegally, and unaware he was under continuous surveillance, and that the other members of his "sleeper cell" were all Federal agents.[2] The agents in his "sleeper cell" had supplied him with inert chemical, so his bomb had not posed a real threat.[4]

Immigration officials were trying to determine how Smadi was able to work at a gas station, since he only had a 2007 tourist visa.[1][3]

Smadi was provided with a fake bomb by FBI agents posing as members of al-Qaeda. He placed the device in the parking garage under the building and activated it with a cell phone. Instead of setting off a bomb, the cell phone rang a phone number at the FBI offices. Smadi pleaded guilty to attempted use of a weapon of mass destruction.[1] Under the terms of a plea bargain, an additional charge of bombing a public place was dropped, and a sentence of not more than 30 years was recommended.[1][5] On October 20, 2010, he was sentenced to 24 years imprisonment. He will be deported from the United States after serving his sentence.
