Hi LS

Was your sentence by any chance taken from the news?

Hi, Amy !

No, it was taken from this site, from one of Alan's tests.

(Do you mean that in the news they always narrate in the present simple tense ?)

Hi LS

The sentence is similar to "reported speech". The tense most likely to have been used in the direct speech is the present perfect:
"Some criminals have broken out of gaol, so be on the lookout for them."

In "reported speech", the verb tense back-shifts and the usual back-shift for the present perfect is the simple past tense.

I don't see the use of the simple past tense as something that would cause any confusion in the sentence, but you can also use the past perfect.
