New York City police are hoping to interview a nanny after two children were discovered stabbed to death in a luxury apartment on Thursday evening.

Yoselyn Ortega, 50, is in a critical condition with self-inflicted stab wounds to her neck, say police.

The children's mother, Marina Krim, returned to her Manhattan home to find the bodies of two-year-old Leo and six-year-old Lucia in the bath.
