A Thai house painter cut off the penises of two teenagers with a knife after he found out they had stolen 50,000 baht ($1249 US dollars) of his savings from an ATM machine, police say. Manit Srithammathan, 40, told police the teens, now in hospital, deserved the punishment as they had betrayed his kindness in letting them stay at his Bangkok suburban house, they said on Saturday. "There's nothing they deserved more for stealing the money I saved that could have helped me get a job abroad," a police spokesman quoted him as saying.
