Mr. Chekkouri was a client of Reprieve and it has issued a press release raising concerns about Mr. Chekkouri's well being in Morocco. This suggests to me that he must have been released sometime earlier.
Reprive's statement can be found here.
The prison population stands at 115: 53 are cleared, 52 are awaiting clearance, and 10 are in the military commission system (of those, 7 are in “active” “trial” proceedings while 3 have been “convicted”).

Of the 52 awaiting clearance, 24 are Yemenis and 28 are non-Yemenis.
