Answer 2

Answer:

Here 'police has caught the theif' sentence is in simple past tense, which gives the straight meaning of police catching the thief.

If we try to transform this sentence into past negative it becomes "Police has not caught the thief", hereby adding 'not' adds as the negative meaning for the past tense statement
