ARA, Jan. 24 -- With the arrest of a young man identified as Rupesh Kumar Chaubey, the Central Bureau of Investigation (CBI) appears close to cracking the mystery surrounding the kidnapping of a teacher Kamlesh Rai, a resident of Kolharampur village in the Barhara block of Bhojpur district, who went missing on July 13, 2023.

According to officials familiar with the probe, Chaubey hails from Buxar district and was pursuing his studies in Patna while working part-time. An officer said that besides following other leads, the CBI is now searching for the accused's alleged fiancee. The agency also suspects that Rai may have been murdered due to a love triangle, officials said.
