Prince George’s County authorities placed Potomac High School on lockdown for about an hour and a half Wednesday morning as police responded to a call for a shooting nearby in Oxon Hill.

At about 9:15 a.m., a woman called 911 reporting that two men, one with a gun, confronted her, said Officer Harry Bond, a spokesman with the Prince George’s County police department.

“According to the victim, the suspect shot the gun in the air before fleeing the scene,” Bond said.

Schools officials and police said the school was placed on lockdown as a precautionary measure for the activity outside of the school. The lockdown was lifted at about 10:50 a.m., Bond said.

“There is no information leading us to believe the school is associated with the call for the shooting,” Bond said.

Police don’t yet have a description of the suspects, Bond said.
