Amarita Khan, 23, was found sprawled on the sidewalk in a pool of blood

A knife-wielding man stabbed his wife again and again on a Bronx street Saturday, killing her in gruesome fashion in broad daylight, police said.

Amarita Khan, 23, was found sprawled on the sidewalk in a pool of blood — unconscious and unresponsive — on Hone Ave. in Morris Park about 6:14 p.m., cops said.

Khan, of Richmond Hill, was rushed to Jacobi Medical Center, where she died.

Her husband, who was found covered in blood, was cuffed at the scene, a police source said. Charges against him were pending late Saturday night.

The couple was in the Bronx visiting relatives. Neighbors said they were stunned by the sudden spasm of violence.

People were setting up for a party about four doors down from where the killing took place, but the attack happened too quickly for anyone to intervene, a police source and people on the block said.
