BROOKLYN, N.Y. - The Metropolitan Transportation Authority is investigating after a Hasidic man said he was the victim of an anti-Semitic incident on a bus in Brooklyn.

It comes as the borough's Orthodox Jewish community is dealing with a major measles outbreak.

The United Jewish Organization of Williamsburg says a man was waiting on the corner of Flushing and Franklin Avenues last week, when the B57 bus passed him by.

He eventually caught up and the driver let him in. That's when she allegedly covered her face and said, "Go in, measles."

The UJO calls the driver's actions anti-Semitic.

Mayor Bill de Blasio condemned the alleged incident.

The MTA says it is cooperating with the investigation.
