Does anyone know who the buffoon is in charge of Cleveland police and where i can get his address?

2310hrs, the quiet pub in my area (Marton) was aggressively raided by cops looking for "drugs" all the young guys who do drugs had all gone down the town as you might expect, and the only men in there were over 50s finishing off thier drinks before walking home. My 56 year old fater was accosted and searched! Apperntly it was "intelligence led" but its entirely ludicrous, i could understand it earler in the evening but after last orders? Anyway, its a first for me cos im not a whiny liberal, but i actually want to write a letter of complaint to the utter buffoon that thought this was a good idea. So, does anyone know, who would have sanctioned this action (i presume chief constable?) and where i can get his name and address in order to send him a letter?
