Police are searching for a man accused of a public lewdness pattern across Brooklyn.

According to police, a 29-year-old woman aboard the F train Sunday near the Prospect Park subway saw a man expose his genitals and perform a lewd act right across from her. The second incident was on Wednesday on a F train approaching the Ditmas Avenue station. Investigators say a 40-year-old woman witnessed the suspect doing the exact same thing.

The victims were not physically hurt.

Anyone who recognizes the suspect is asked to call police.
