According to an unreferenced law firm’s website,
As a general guideline, you may be able to claim around £870 for the first hour of false imprisonment, which increases to around £5,210 for 24 hours.
In some cases, you may also be entitled to claim aggravated and exemplary damages, however it is rare for these to be awarded. Aggravated damages can be awarded where the police have deliberately acted to cause injury to feelings or where basic damages are insufficient.
Exemplary damages are damages meant to punish the police for oppressive, arbitrary or unconstitutional action.
What case(s) lay(s) down these figures, and which set(s) out the parameters of exemplary and/or aggravated damages in such cases?
