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

'detained' is the definition.
Although both the answer and definition are past participle verbs, I don't understand how they can define each other.

'held up in federal lockdown' is the wordplay.
'held up' says the letters should be written backwards.
'in' says the answer is hidden in the clue.
'deralloc' is hidden in the letters of 'federal lockdown'.
'deralloc' reversed gives 'COLLARED'.

'being' acts as a link.

Can you help me to learn more?

(Other definitions for collared that I've seen before include "Apprehended (colloq.)" , "like some doves and peccaries" , "Seized" , "Caught - variety of dove" , "Captured" .)
