"Initial investigation revealed that their throats were slashed with a sharp object. Some other injury marks were found on their mouth, stomach and other parts of body. It seems that the attacker tried to rape the girl child," said the officer.
Police said that the victims, resident of east Delhi's Khajuri Khas, are survived by their parents Akram, a contractor, and mother Naseema Begum.
"On Tuesday around 3.30 p.m. both the siblings were seen playing in the street near their residence. Their parents registered their missing complaint late Tuesday night," said the officer.
