Rushed out thus, attempted to turn first pair (7)

'rushed out' is the definition.
Both the answer and definition are past participle verbs.
Perhaps you can see an association between them that I can't see?

'thus attempted to turn first pair' is the wordplay.
I cannot quite understand how this works, but
'thus' could be 'so' ('so' can be a synonym of 'thus') and 'so' is found within the answer.
'turn' could be 't' (abbreviation in Oxford Dictionary of Abbreviations) and 't' is present in the answer.
'first' could be 'i' (I in Roman numerals eg Elizabeth I) and 'i' is located in the answer.
The remaining letters 'red' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
