Federal prosecutors filed federal hate crime charges against the man accused of stabbing five people at a Hanukkah celebration in Rockland County over the weekend, according to the New York Times.

The FBI is investigating Grafton Thomas' mental health history, according to the report. His family says he has a long history of mental health illness and no history of religious hatred. Thomas pleaded not guilty to five counts of attempted murder Sunday. Bail was set at $5 million, according to authorities.

NYPD officers arrested him Saturday night in Harlem after license plate readers sent an alert that his car crossed over the George Washington Bridge.

Investigators say Thomas stormed into the home of a rabbi just hours earlier and stabbed five people in Monsey, New York, which is about 35 miles north of the city.

One person is still in critical condition, according to Governor Cuomo.

Cuomo has directed the state’s Hate Crimes Task Force to investigate the attack, calling it an act of "domestic terrorism," in an interview on NPR.

Meanwhile, civil rights and religious leaders met in Harlem today to denounce the spike in anti-semitism in our area.

Mayor de Blasio says city leaders are working to ensure attacks like this do not become the new normal.

The mayor stood in solidarity with the Jewish community in Brooklyn yesterday, taking part in a menorah lighting at Grand Army Plaza on the eighth night of Hanukkah.

During an earlier news conference, de Blasio and the NYPD said they are increasing the number of cameras around the city, including Williamsburg, Crown Heights and Borough Park.

They also announced the creation of a neighborhood safety coalition to help bridge any divide between residents and neighborhoods.

"It is crucial to say that these actions will have a powerful impact, but as we know from all of our efforts over the years and the fight against terror and the fight against crime, the NYPD cannot do it alone. [It] requires the active assistance of all New Yorkers," de Blasio said.

The mayor also said an anti-bias curriculum will be added in city public schools.
