Three more skulls have been found near the home of an Indian businessman and servant arrested for alleged multiple rape and murder, Indian media say.
Distraught relatives are maintaining a vigil
The discovery could bring the number of bodies found in Noida, a suburb of the capital Delhi, to 20.
Reports quoted Central Bureau of Investigation detective, who took over amid anger at local police inaction. The CBI has not confirmed the new find.
Angry locals are continuing to hold a vigil outside the suspect's home.
Businessman Maninder Singh Pandher and his servant Surendra Koli are being questioned over the murders.
Lie detector test
Local media quoted CBI detectives as saying they had found the three skulls while searching drains near the home on Saturday night.
However it was unclear if they belonged to the suspected 17 victims already discovered, or added to the number.
The Hindustan Times said a bag containing human body parts, bones and clothes was also pulled from the drain.
CBI spokesman G Mohanty refused to comment on developments when contacted by the BBC.
Residents say as many as 40 children have disappeared in the area over the past two years.
Parents of some of the missing children are holding a vigil at the home, shouting "killers, killers" and demanding those guilty be executed.
The two suspects were arrested two weeks ago and are being held on suspicion of multiple abduction, rape and murder.
The CBI was granted the custody of the accused on Thursday for 14 days. The accused have undertaken lie detector tests.
The crime has shocked the country with many people accusing the local police of negligence and dereliction of duty.
Many locals say police failed to act over the abductions and murders because many of those reported missing came from poor families.
Six Noida policemen have been sacked for alleged incompetence. Three senior officers are suspended.
