Though the family has not received any ransom call, the kidnapping angle has not been ruled out yet, Kasna police said.
They said the room mates of Akash Yadav have been questioned and his mobile phone was recovered from the rented flat he was staying in.
The victim is a resident of Sikandarabad. He was studying engineering at IILM college here and was a final year student, a senior police official said.
Akash's father Pappu Yadav is a Samajwadi Party leader, and also has a transport business.
SP general secretary Ramjilal Suman has approached IG, Agra and SSP, Noida, for the safe recovery of Akash.
