Montgomery County police are investigating a Gaithersburg man — currently held in jail — who they think may have sexually assaulted a series of men over the last 10 years, officials said Monday.

The police began their case against Joey Poindexter, 38, last month after learning that he met a victim at Looney’s, a bar in College Park, the night of Oct. 3 and into the morning of Oct. 4. The two went back to Poindexter’s residence in Gaithersburg, police said, where the victim was sexually assaulted.

“There are likely additional victims,” police said in a statement.

Online court records indicate that Poindexter was represented by a public defender at his bond review. The records do not identify a specific attorney assigned to his case.

Police officials have called a news conference for Tuesday morning to discuss details of the case.
