The police on Sunday arrested a youth and two minors on charges of kidnapping and murdering a 14-year-old school student.
One of the arrested was a victim's neighbour. The trio had kidnapped Govind Mali, a student of class VIII, from near his home on Friday night and took him to Balotara, they said.
On Saturday, Govind's father, a two-wheeler mechanic, received a ransom call from the kidnappers who demanded Rs 5 lakh for the release of his son.
The trio, however, allegedly strangulated the boy, stuffed his body in a gunny bag and threw it in the drain.
