EAST JAVA, INDONESIA — Envy is one of the deadly sins. Also on that list ought to throwing acid in someone’s face. Because that’s exactly the horror that befell 24-year-old Indonesian karaoke hostess Citra Rey on March 5 in East Java. The culprit: her jealous boyfriend.

Citra had been with her long-term boyfriend, Lamaji, for some six years. But in recent months he’d began to suspect she had been seeing another man behind his back.

And, at dawn on Sunday, his suspicions were confirmed when he caught his beloved in the back of a white Honda, doing the dirty with her 44-year-old sugar daddy.

Lamaji had clearly been stalking her, for when Citra exited the car, he threw his container of hydrochloric acid right into her face. Lamaji ran - leaving the girl he once loved screaming in agony.

Later that morning, Lamaji was arrested at his cousin’s home as he lamely tried to hide from police.

Meanwhile, Citra was hospitalized and is undergoing treatment. The extent of her injuries has not been reported.
