Rats risen from ground (9)

Ross

I believe the answer is:

informers

'rats' is the definition.
('informer' can be a synonym of 'rat')

'risen from ground' is the wordplay.
'ground' is an anagram indicator (grind the letters ).
'risen'+'from'='risenfrom'
'risenfrom' anagrammed gives 'INFORMERS'.

I've seen this clue in The Telegraph.
