As is the link enabling you to report minor crimes on the national police web site.
D Division can be e-mailed through the Nottinghamshire Police web site.
The same site shows the contact phone number for West Bridgford Divisional HQ as 0115-940-0999 and says that the opening hours are 24 x 7. Not my experience, I think you will be lucky to find it open at all.
The business section of the Nottingham telephone directory gives the
number as 945 5999.
