Gluing Two Sentences with "as"

[flagofsurrender]

Suppose you have the sentence:
Tom and John ran without stopping as a strange man continued to chase them down a dark and narrow alleyway.

If I were to translate this into Japanese, is there a way to glue what is actually two sentences with a Japanese equivalent of "as" or is it better to break the one sentence into two?

A -te form is fine here.

Well, I'm giving it a try. I know this should probably be in the Japanese Practice board, but I figure it still pertains to what we are discussing.

トムとジョンが停まらずに行くっては見知らね人追いかけてに下路地。

I'm pretty sure that I am missing some particles in here. I also left out a word or two...I think.
