Incidents involved Devon temples (12)

I believe the answer is:

developments

'incidents' is the definition.

'involved devon temples' is the wordplay.
'involved' indicates anagramming the letters (involved can mean confusing or complex).
'devon'+'temples'='devontemples'
'devontemples' anagrammed gives 'DEVELOPMENTS'.

(Other definitions for developments that I've seen before include "Progressive changes" , "Fresh events" , "Move Len's dept (anag.)" , "Advances in a process" , "MTD envelopes (anag.)" .)

I've seen this clue in The Telegraph.
