Federal officials believe suspected Islamic terrorists are in the United States and that a Somali man in custody helped them in through Mexico and Texas

A Justice Department memo and other documents says that federal officials believe the suspects, who remain at large, are members of East African groups. In Spring 2010, U.S. Homeland Security officials issued an alert asking Houston-area law enforcement to be on the lookout for a suspected member of the al-Shabaab group, an al-Qaida ally based in Somalia. That was after the new charges were added against 24-year-old Ahmed Muhammed Dhakane, who had been picked up in Brownsville in 2008. On Nov. 2 2010, Dhakane pleaded guilty to making false statements in support of his asylum application and is to be sentenced April 28 2011.
