DENVER -- A Pakistani man who was convicted of illegally entering the United States has been deported.

U.S. Immigration and Customs Enforcement officials say Raja Ur Rehman Siddiq, 40, had been selling identification cards at his "dollar store" business in Colorado Springs, Colo. The cards reportedly resembled official state identification cards, but had disclaimers on them that said the cards were not "government issued."

Immigration officials say undocumented aliens had used cards to get into secure military installations in and near Colorado Springs.

"Anyone who knowingly and indiscriminately sells phony identity cards is putting the security of our communities and even our country at risk," said Scott Johns, the assistant chief counsel for ICE in Denver. "Documents like this could potentially be used by terrorists or other dangerous criminals to obscure their identities and cover their tracks."

Authorities say Siddiq had been in U.S. custody since April 2003. He was sentenced to time served on the illegal entry charge and returned to immigration custody early this year. An immigration judge ordered him deported last month, and authorities say he arrived in Pakistan on Sunday.
