Seattle police are looking for a man accused of stabbing a woman with the stiletto heel of her own boot.

A police report said the man attacked the woman at a June 29 barbecue at a friend's house.

The 40-year-old Tukwila woman suffered an injury to her left hand that required surgery Saturday for an aggressive bacterial infection.

The man had asked the woman to perform a sex act and when she refused he slapped her face, removed her boot and stabbed her with the heel, the report said.
