Police are looking for a man who threw urine on two female MTA workers, officials said Sunday.

The man, who was believed to be in his 20s, punched an on-duty MTA conductor in the head and threw a cup of urine in her face inside of the Brook Avenue “6” subway station at about 10:30 a.m. Friday, police said.

About an hour later, cops said the same man threw another cup of urine at a bus driver through an open window while she was behind the wheel of the BX 2 bus on Grand Concourse Avenue near East 138th Street.

The MTA workers, both 43-years-old, were taken to nearby hospitals, where they were treated and released.

The NYPD released a photo of the man Sunday to help ID him.

The Transit Workers Union also asked for the public’s help to find the urine thrower.
