Stick up hotel, beset by drunk police still (7)

I haven't cracked this one yet — but the brilliant team at Times for the Times have:

GUM (stick) reversed [up], then H (hotel) contained [beset] by SOT (drunk). Note: Early posters have pointed out that MUG (stick up) without reversal also works and on reflection I agree although when I first considered it when blogging I wasn’t sure that that ‘mug’ and ‘stick up’ were necessarily quite the same thing.
