BATON ROUGE, La. (AP) — State and federal agents descended upon the Kenilworth Science and Technology Charter School and carted away boxes from the Baton Rouge school.

But details of their investigation remains a closely guarded secret, as school and law enforcement officials refused to discuss the reason for Wednesday night's visit.

More than a dozen agents wheeled several boxes to unmarked white van parked by the front doors.

School officials, including Principal Hasan Suzuk, referred inquiries about the raid to Mark Lambert, a spokesman for the charter school, who was equally tight lipped. Lambert said the school is cooperating fully with law enforcement and classes would resume Thursday.
