A participial phrase

The next morning, Carlito captures Dr. Barnaby, and upon being spotted on the security room's monitors suspending him over a group of zombies, forces Brad and Frank to rescue the doctor, the former being wounded in the effort. While seeking medicine for Brad in from the supermarket pharmacy, Frank rescues a young woman from the store's crazed manager, who runs off after he recognises her from earlier and attempts to question her.

I'd like to know if "suspending him over a group of zombies" qualifies "forces."
Thank you in advance for your help.
