BROOKLYN - Police have released a sketch of a man wanted for flashing a woman on the subway in Brooklyn.

According to investigators, the suspect exposed himself to the woman on a southbound 4 train as it approached the Saratoga Avenue stop last Wednesday. They say he forced her against a wall so she couldn't leave, but she was able to run when the doors opened.

The man is believed to be about 25 years old and 6 feet tall.
