The members of People's Action Committee, a panel formed by locals here to seek justice for Chanam, said in its statement the case has been hanging in balance for the past two months but there seems to be no progress yet.
Chanam had gone to Greater Noida to attend a musical concert on September 8 and went missing thereafter.
Four days later, on September 13, his body was allegedly cremated by authorities at Dr. BR Ambedkar Rao Hospital in the district without notifying family members.
"It has been almost two months since the incident occurred at Greater Noida but till date we have no proper knowledge on how the 22-year-old youth died," the statement said.
