ARLINGTON, TEXAS — Officers from the Arlington Police Department are under investigation after one cop Tased a suicidal man who had soaked himself in gasoline. <br /> <br />Officers were called to deal with Gabriel Olivas, 38, on Monday afternoon after two women reported a mentally ill man was threatening to hurt himself, reported NBC 5 Dallas Fortworth. <br /> <br />Olivas had covered himself in gasoline and was also reportedly holding a lighter. Police told NBC 5 that he continued to douse himself with fuel as they tried to calm him down, then began acting erratically. <br /> <br />Deeming him a threat to everyone in the room, one of the cops decided to subdue Olivas with a stun gun. That's when Olivas ignited. <br /> <br />The cops used blankets to put out the flames. Olivas survived, but suffered burns to most of his body. <br /> <br />What remains unknown, reports Dallas News , is if it was the lighter Olivas was holding or officer's stun gun that sparked the fire. <br /> <br />Olvias's wife told NBC 5 a different story. "They tased him. They knew he had gasoline. The officer said, 'If I tase him… he's gonna light on fire." And that's what they did, not even a second later." <br /> <br />The officers involved have been placed on administrative leave until the case is resolved.
