A social justice warrior has claimed responsibility for the bombing in the New York City neighborhood of Chelsea on Saturday night.

CBS News has reported that federal investigators are looking into a Tumblr account called "NY bomber" where a social justice warrior claims to have laid the bombs to fight the oppression inflicted by white men on LGBTQ+ people.

“You probably have all seen the news by now, the explosives detonated in New York City; that was me. Those were just some tests; I know where I have made errors, and I will not make the same mistake next time,” a post said.

The post's author then went on a tirade against straight white men, police officers, and Donald Trump.

“I cannot live in a world where homosexuals like myself as well as the rest of the LGBTQ+ community are looked down upon by society,” the post continued. “It is 2016 and we are still being viewed as mentally ill, sinners, attention seekers, and just plain weirdos in general. I am not going to stand by while under classed and underprivileged people are oppressed. I am not going to stand by while there is inequality in my country such as the racism being seen in white police officers all over the country. I am not going to live in a country where it is OK to have a misogynist, xenophobic, racist Islamophobic, republican candidate running for President of The United States! That’s implying that republicans in general should even be taken seriously as they are all cisgendered privileged white people.”

It concludes with announcing that there will be more targets and enemies will be eliminated.

The Tumblr was taken down sometime early Sunday, and federal investigators said they were looking into additional suspects. A woman claims she saw a man of Arab descent looking out of place and carrying a suitcase that could have contained the homemade, pressure-cooker bomb.

According to The New York Post, a hand-written letter written partially in Arabic was found inside a plastic bag that held the second bomb that did not blow up.

Media outlets are also claiming that the bombs in both Chelsea and Seaside Heights, N.J. may have been linked. The Tumblr account did not take credit for targeting Seaside Heights.

ISIS has claimed responsibility for the other attack that occurred on Saturday at a Minnesota mall.

UPDATE:

The FBI put out a message that they are seeking information on Ahmad Khan Rahami in connection with the bombings in New York City.
