Arrest students behind Tehran explosion (8)

I believe the answer is:

enthrall

'arrest' is the definition.
(thesaurus)

'students behind tehran explosion' is the wordplay.
'students' becomes 'll' ().
'behind' says to put letters next to each other.
'explosion' indicates anagramming the letters.
'tehran' with letters rearranged gives 'enthra'.
'll' put after 'enthra' is 'ENTHRALL'.

(Another definition for enthrall that I've seen is " Fascinate (US spelling)".)

I've seen this clue in The Hindu.
