There is no statute with that number. The number must be code for something else but I don't have a clue what it might be. Maybe it means he is on a US Marshall courtesy hold.

The Marshals are Feds. If they apprehend a fugitive, they may not be near a federal detention facility. So they hold prisoners at a local facility until they can arrange a transfer to a federal or contract facility.
