The Delhi Police, who are assisting the Rajasthan Police in connection with the body of a woman found in a parcel in Kishangarh, Ajmer, have been unable to gather much information in the case.
The police have not been able to identify the woman yet.
The police said they, along with Rajasthan Police, have examined the CCTV footage available at the office of the courier company from where the parcel was sent.
"We have examined it but nothing concrete has been found till now," said a senior police officer on condition of anonymity.
The Ajmer police have sent one more team, headed by a Station House Officer, to Delhi in connection with the probe.
The police suspect the victim was raped, though a medical test and post mortem are yet to be conducted.
In a bid to get clues about the sender of the parcel, the police are searching CCTV records availed from Milap Transport Roadlines Company (MTRC) of Pili Kothi, Old Delhi.
The teams have so far been unable to get clues and the victim has also not been identified.
The police had, on Friday, recovered the dead body of the girl, in her early twenties, from a tin box, dispatched as parcel from MTRC to Krishna Transport Company (KTC) in Kishangarh, Ajmer.
"We have so far got no clue in the case but teams are busy in searching the CCTV footage of the parcel company and nearby locations. The Delhi Police are also investigating the case," said Bipin Kumar Pandey, Ajmer Superintendent of Police.
"The Ajmer police have pinpointed negligence of MRTC employees in not getting proper addresses of the dispatcher and the receiver of the parcel. But only Delhi Police can take action against the company," Pandey added.
The date on the receipt has also tempered been tampered with. While one date mentions March 31, it has been overwritten as April 2.
"This is clear negligence on the part of the sender company," said Narendra Singh, SHO, Madanganj police station, Ajmer.
Singh said a murder case has been registered against unidentified persons.
The dead body was found in a mutilated condition. It had stab wounds and the face, too had been burnt.
