Sympathies, sounds like you crossed paths with a twat that day .
And some cop who lacks the balls or common sense to tell the twat to just drop it
To paint the picture clearer of the twat:
- Born in 1971 (I saw on his HKID)
- Somewhat mentally deranged (I honestly believe)
- Most distinct facial feature - giant mole in the middle of his forehead (like Nancy Sit ka yin lol).
The legal position he took (with the help of his lawyers) was 'shut the fuck up friday'. Eventually the investigating was shelved for lack of evidence.
I never sign - ever. You cannot be compelled to sign. A sergeant or higher rank may counter sign an addendum noting your refusal to sign.
Your duty - identify your ID details, address, vehicle and that of the owner/driver if not the same.
Do you have the badge number / name / rank of the officer asking you for information on Whatsapp?
That should also give you a clue as to which department / station is handling your case.
I guess it is "the more than my job is worth" process, one step is taking statement, logically they will pursue OP (forever) until they get that statement, before they can move to next step..... perhaps it is a lost opportunity to record and reiterate that attending police officer found no evidence of accident?
