HOUSTON (KTRK) -- Three former Houston police officers are now indicted on charges following a ticket-writing scandal.



We've confirmed a grand jury indicted the officers Friday morning. Gregory Rosa, John Garcia and Robert Manzanales are all indicted for tampering with government documents. Manzales also has an additional charge of aggravated perjury.



The officers resigned or retired after an internal HPD investigation started last year into extra overtime pay.



Investigators looked at whether the officers falsely claimed to be at traffic stops that resulted in tickets.



A fourth officer under investigation committed suicide.
