A man accused of exposing himself at a bus stop could be linked to other crimes, DeKalb County police said Friday.

The most recent incident occurred June 6 around 11:45 p.m., when a woman told police a man approached her while she was at a bus stop at the intersection of Covington Highway and Mercer Drive, according to Mekka Parish, DeKalb police spokeswoman.

“The man attempted to engage her in a conversation and when she turned to address him, she observed him committing a sexual act,” Parish said in an emailed statement.

The woman left the bus stop and called police, who searched the area with the help of a police dog, but could not locate the suspect, Parish said. Investigators hope a sketch released Friday helps identify the suspect.

Police also want to determine if the same suspect had a role in two previous attempted sexual assaults that occurred nearby at the Marquis Ridge Apartment complex.

On May 31 around 4 a.m., a suspect entered an apartment through an open window, found two female victims asleep on a couch and then performed a sexual act in front of them, Parish said. The victims, ages 28 and 30, screamed as they awoke and the man left, according to police.

Then on June 3, around 4:40 p.m., a 10-year-old girl was asleep in her bedroom in an apartment and awoke to a man standing in front of her performing a sexual act, police said. The victim screamed and ran to alert her parents in another area of the apartment. The suspect had gained access to the apartment through an open window.

Anyone with information about the case is asked to call the Special Victim’s Unit at 770-724-7710.
