Removing crankset

Does anybody know how to remove this type of crankset? (See Pictures)

8mm Allen key in the centre and unscrew - it's a captive screw - you'll probably need some extra leverage from a regular Allen key to get it going.

Looks like a self extracting bolt, so in principle you only need the correct size Allen Key...

looks like it could be octalink shimano 105, these might help...

Thanks for the help, 10mm Allen Key did the job.
