Kanpur: The family of a 27-year-old lab technician, who was kidnapped and later killed, on Saturday demanded a CBI probe into the matter.
Five people, including a woman and two friends of S Yadav, have been arrested in connection with the case, according to police.
The man's sister Ruchi Yadav met Additional Director General (ADG-Police Headquarters) B P Jogdand and demanded a CBI probe into the case suspecting that there could be more people behind the killing.
She told the ADG that the police has failed to recover her brother's belongings, including a couple of bags, mobile phone, wallet and ATM card.
The family members of S Yadav had earlier appeared before the media and claimed that they had thrown a bag containing Rs 30 lakh from a flyover to railway tracks in the presence of police and also did whatever the kidnappers demanded, but the accused did not free the victim.
Circle Officer Vikas Pandey had said that no ransom money was paid for his release in the presence of police and the allegation was not true.
