Carrier in Tangier evacuated? Indeed (4)
I believe the answer is:
tray
'carrier' is the definition.
(I've seen this before)
'tangier evacuated? indeed' is the wordplay.
'evacuated?' means to remove the middle letters.
'indeed' becomes 'ay'.
'tangier' with its middle removed is 'tr'.
'tr'+'ay'='TRAY'
'in' is the link.
(Other definitions for tray that I've seen before include "platter" , "Board for carrying items" , "'It's used for carrying, crockery say (4)'" , "Portable carrier" , "Flat carrier" .)
