Absolving the youths of the penal charges, Additional Sessions Judge Ashutosh Kumar ordered their forthwith release from jail where they had been lodged for over nine months.
The court observed that neither the girl nor the medical report confirmed the rape and even the alleged victim did not identify the accused.
"Thus, from the testimony of the three witnesses (girl and her parents), it is clear that there is nothing incriminating against the accused persons," the judge said.
"Even, the medico-legal case of the girl does not show that any rape was committed upon her," he added.
It further said all three accused were in judicial custody since November 2011. "They be released forthwith, if not required in any other case."
According to the prosecution, the 14-year-old girl was allegedly kidnapped by the four boy on November 11, 2011, when she was on her way to school. However, the fourth one was declared proclaimed offender during the course of trial.
It said that the accused had taken her to a secluded spot in a car and took turns to rape her.
