Man following me in Prospect Park

Posting here because a man was following me in prospect park for about half a mile. I changed tracks several times and he kept following me. I went down to sit on a bench and lost him. I came back onto the main walking path after about five minutes and he had stopped waiting for me to pass by and immediately started walking behind me when I passed him. He is an around five nine, red zip up, black man, late 20s/early 30s. He just walked out toward grand army plaza after I walked into the middle patch of grass and yelled at him to stop following me. Please beware!

edited to add last part about how I got him to stop following me
