Sacks many taking nothing in (5)

I believe the answer is:

loots

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

'sacks' is the definition.
(to sack is to loot or pillage)

'many taking nothing in' is the wordplay.
'many' becomes 'lots' (lots of something).
'taking nothing' becomes 'o' (looks like zero - 0. I am not sure about the 'taking' bit.).
'in' is an insertion indicator.
'lots' enclosing 'o' is 'LOOTS'.

Can you help me to learn more?

(Another definition for loots that I've seen is " Steals".)

I've seen this clue in The Irish News.
