Arriaga

Arriaga was a Starfleet lieutenant assigned to Deep Space 9 in 2372.

In that year, under orders from Admiral James Leyton, he attached a subspace modulator to the relay station on the Gamma Quadrant end of the Bajoran Wormhole, which caused the wormhole to open and close at random, and create the fear that cloaked Dominion starships were entering the Alpha Quadrant. This was discovered by the crew of DS9, and Arriaga was brought to Earth aboard the USS Defiant to testify against Leyton.
