New hospital - rats all over the place, no real punishment (1,4,2,3,5)

Ross

I believe the answer is:

a slap on the wrist

'no real punishment' is the definition.
(a slap on the wrist is a light punishment)

'new hospital rats all over the place' is the wordplay.
'all over the place' is an anagram indicator.
'new'+'hospital'+'rats'='newhospitalrats'
'newhospitalrats' anagrammed gives 'A SLAP ON THE WRIST'.

(Other definitions for a slap on the wrist that I've seen before include "Some stick" , "reprimand" .)
