Ninety-two Somali immigrants, set to be deported from the US, found themselves shackled at the hands and feet and kept aboard a plane for two days earlier this month. That part of the story is not in dispute.

The Somalis left Louisiana on Dec. 7. Their flight, chartered by US Immigration and Customs Enforcement, was bound for Mogadishu, the capital of Somalia. But the plane never arrived.

After landing in Dakar, Senegal, on Africa's west coast, the one-way flight became a round trip, back to the US. Why that happened, though, remains subject to dispute.

The 92 immigrants, now being held at the Krome and Glades detention facility outside Miami, are consulting with their lawyers.
