Jack the Ripper copycat taking pee? He sprays all over the place (8)

'jack the ripper copycat taking pee? he sprays all over the place' is the definition.
The definition suggests a singular noun which matches the answer.

'he sprays all over the place' is the wordplay.
I cannot quite see how this works, but
'he' could be 'asher' and 'asher' is located in the answer.
'place' could be 'pl' (abbreviation used in postal addresses) and 'pl' is present in the answer.
A single letter 's' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
