Well, now police vehicle attends attack on uniform (2,3,5)
I believe the answer is:
up and about
'well' is the definition.
(thesaurus)
'police vehicle attends attack on uniform' is the wordplay.
'police vehicle' becomes 'panda' (I am not sure about this - if you are sure you should believe this answer much more).
'attends' means one lot of letters go next to another.
'attack' becomes 'bout' (eg a bout of flu).
'on' says to put letters next to each other.
'uniform' becomes 'U' (phonetic alphabet: alpha, bravo, charlie etc.).
'panda' put next to 'bout' is 'pandabout'.
'pandabout' after 'u' is 'UP AND ABOUT'.
'now' is the link.
Can you help me to learn more?
(Other definitions for up and about that I've seen before include "Ready to start the day" , "Out of bed and moving around" , "Active" .)
