A prominent national Islamic civil rights and advocacy group today called on the Department of Justice to investigate an incident at a Texas immigration facility that left a Jordanian Muslim detainee in critical condition following a "mysterious" injury to his head. The Washington-based Council on American-Islamic Relations (CAIR) said Khalfan Omari, 25, is recovering from brain surgery following what media reports call "a mysterious incident" at El Paso's immigration detention center. Omari's brother sent CAIR post-operative photographs of the injury that show a 7-inch scar in his scalp. Immigration and Customs Enforcement spokeswoman Leticia Zamarripa told the El Paso Times that Omari said he had "fallen from his seat and hit his head." **PHOTO CAPTION*** The image shows a 7-inch scar in Mr. Omari's scalp.
