The Union Minister of State for Agriculture had demanded the inquiry after a forensic report said the meat sample collected from outside Akhlaq's house belonged to a "cow or its progeny".
"I said there should be an investigation, as the report is before the court. So it may be by the government or the court," Baliyan told a press conference here.
Asked whether more people should be investigated if found that many others had consumed beef there, Baliyan said "It is the job of the police, I can only demand a probe. The report has already come before I demanded the probe.
