Yesterday, police released a sketch of a serial groper who they say may have attacked at least seven different women this year all on the Upper East Side. After an attack early Saturday morning on a 29-year-old woman, it seems the groper attempted to attack another woman early this morning. Heather wrote us with the story of her close encounter with the groper. Check it out below:

Facts: I am a 24-yr-old woman who was coming home late last night from a party. At approximately 3 am Sunday morning (7/17), the groper followed me home from the subway station at 77th (6 line) without my knowledge.

He made contact as I was getting off, asking for directions to 42nd street. At that time, I had no idea who he was. He was small and nonthreatening (he fits exactly the sketch and description published in the news). Acted like he baaarely spoke English. Buck-teethed with a big front gap. A baggy white polo and baseball cap. I told him to catch the downtown train, but I was not friendly by any means. He walked in the opposite direction of me, so I thought.

So I walk about 3 blocks to my walk-up on 78th between 2nd and 3rd, not thinking anything of the encounter. I live on the sixth floor, so I let myself in and then as I am climbing I start hear footsteps softly ascending behind me as I am going up. That was my first clue. I monitor the steps to see if they stop and enter an apartment. They don't -- and when I reach the sixth floor and turn around -- there he is on the landing below me. I loudly say "WHOA, WHOA -- WHAT ARE YOU DOING?" and stare him down. He pauses, wide-eyed, unsure, and then just turns around and runs away. I called the cops once inside, but since I wasn't touched there could be no formal report. They were fairly helpful, though, and seem to be on the lookout. They said I responded correctly...

But LESSON LEARNED: make sure that pesky door closes all the way behind you when you enter a no-doorman apartment. I have been living in my place a long time, and 3 years on the UES, and haven't needed to be vigilant about it -- it swings closed very slowly and there's plenty of time for someone to stick a hand in and stop it.

Cops have described the suspect as a Latino male between the ages of 25 and 30 who is 4-foot-11, 120 pounds and has black hair. Anyone with information about him is asked to call Crime Stoppers at 1-800-577-TIPS (8477).
