Arrested man reversed charges and called informally (9)

Ross

I believe the answer is:

nicknamed

I'm a little stuck... Click here to teach me more about this clue!

'called informally' is the definition.
'nicknamed' can be an answer for 'called' (nicknaming is a kind of calling). I am unsure of the 'informally' bit.

'arrested man reversed charges' is the wordplay.
'arrested' becomes 'nicked' (I've seen this before).
'reversed' is a reversal indicator.
'charges' is an insertion indicator (charge can mean to charge into something).
'man' written backwards gives 'nam'.
'nicked' going around 'nam' is 'NICKNAMED'.

'and' is the link.

Can you help me to learn more?

(Other definitions for nicknamed that I've seen before include "Given handle" , "with additional handle?" .)
