Police have identified the man they believe is behind a series of disturbing attacks targeting Asian women in New York City.

Tyrell Shaw, 25, allegedly attacked his fourth victim around 4 p.m. Monday after trying to start a conversation with a 41-year-old Asian woman in the vicinity of 48 Mulberry St. in Chinatown. When she ignored him, police said, he left -- but returned shortly carrying a gray bag with a hard object inside. He walked up to her and struck her in the face before running away, police said. The woman was taken to a local hospital where she was treated and released.

On his blog titled "Mr. Talented," Shaw wrote several angry blog posts, including an apparent suicide note "Why I Decided To Leave Earth," accusing Asian women of rejecting him because of his skin color.

In less than 350 days, I talked to nearly 1500 Asian Women and none of them took time out of their day to say hello," he wrote. "I became furious. I never agreed with violence, but I knew the only way I could overcome that sense of rejection-would start by assaulting the Women that carelessly rejected me.

He wrote in detail about the attacks, which he referred to as "The Nose Game."

Suddenly, I assumed the ones that I am attracted to use cocaine so I decided to play a game. Bash Asian Women in the Nose so that they could stop sniffing cocaine and give me a chance. At first I thought I could get away with 1 Million Noses, but at 6th victim I felt a little discouraged. I didn't even expect to bash The Dry cleaning lady in the mouth. She went overboard with the verbal abuse. That was actually my day off from playing the Nose Game. Yeah, thats what I'll call it, "The Nose Game."

In his last post he laid out his sick vision:

Heres my plan:

Every Asian Woman by herself must be hit in the face. I may even take a photo before hitting them. The reason is because I don’t think Asian Women like me and that specific one or two or three may have never met me. So I think its brilliant to give all Asian Women a legitimate reason to hate me.

Shaw also vowed to commit suicide, writing:

Inform NYPD they could stop searching for me because I'm going to commit suicide. Actually, I've already tied a noose to the bottom of an elevator and I'm going to wait until someone pushes a button so that its not considered a practical suicide. This is actually murder. Thank you. I love you.

Shaw is believed to have attacked at least three other Asian women in different parts of Manhattan. In all of the assaults, the attacker hit them with a white bag containing a hard object inside, they said. The victims were taken to a local hospital where they were subsequently released.

Police suspect Shaw in the following past attacks:

At 4:15 p.m. Wednesday, a 35-year-old Asian woman was sitting in the vicinity of 155 Grand St. when the attacker attempted to strike up a conversation with her but she victim ignored him. The culprit left but returned with a bag, striking the victim in the cheek/chin area and then fled the scene.

At 8:21 p.m. Wednesday, a 29-year-old Asian woman was walking down Park Avenue when the assailant walked past her and waited at the corner. When the victim reached the corner the culprit struck her in the face with a white plastic bag, then running away.

At 12:25 a.m. Friday, a 34-year-old Asian woman was walking in the vicinity of Second Avenue and East 60th St. when he struck her in the forehead with a bag.
