Dismisses detective from NE town? (3-5)

I believe the answer is:

red-cards

'dismisses detective from ne town?' is the definition.
'red-cards' can be an answer for 'dismisses' (to dismiss from the pitch in football). I am not certain of the 'detective from ne town?' bit.

'dismisses detective' is the wordplay.
'dismisses' becomes 'redcar' (I can't explain this - if you can you should give a lot more credence to this answer).
'detective' becomes 'DS' (detective sergeant).
'redcar'+'ds'='RED-CARDS'

I've seen this clue in The Times.
