State in which criminal teen's seen (9)
I believe the answer is:
tennessee
'state' is the definition.
(Tennessee is an example)
'criminal teen's seen' is the wordplay.
'criminal' indicates anagramming the letters.
'teens'+'seen'='teensseen'
'teensseen' with letters rearranged gives 'TENNESSEE'.
'in which' is the link.
(Other definitions for tennessee that I've seen before include "Famous American playwright . . . . . . . . . Williams" , "Teen sense observed in American state" , "Seen teens in this US state" , "Williams, say" , "US state, capital Nashville" .)
