man exposed himself yesterday afternoon

See this Wednesday, 3/30/2011 message from a Thomas Street NW resident:

``Had a disturbing experience at my house today. My mother, who is 84, is visiting. She was reading in my bay window early to mid afternoon when a man who had been hanging out on the street for a while stepped up on to my porch sat down and pulled his erect penis out of his pants and played with himself. Shortly thereafter my mother looked up and noticed this. She stood up and walked away. Has this happened to anyone?``
