New Delhi:
A brother-sister duo were found murdered at their residence in central Delhi on Monday, police said.
Vishal, 19, and his sister Shivani, 23, were found dead at around 8.45 pm by their father with head injuries on the first floor of their Ranjit Nagar residence. They were rushed to a nearby hospital but both were declared brought dead.
A senior police official said they were investigating the motive behind the crime.
"The entry into the residence was friendly, so we assume that some known person or persons are behind the crime," he said.
The victim's father runs a restaurant in front of Pusa Institute here.
