A high school graduation party in Severn erupted into violence Sunday morning, resulting in at least five people injured, Anne Arundel County police said.

According to a press release from police, officers responded at 12:58 a.m. Sunday to the 7800 block of Citadel Drive in Severn, initially to a report of a loud party. While they were enroute, they received calls that shots had been fired at the same location.

Officers arrived and dispersed a large crowd, and then found a 17-year-old boy with a gunshot wound to the leg. He was transported to the Maryland Shock Trauma Center in Baltimore with non-life threatening injuries.

While on the scene, officers learned that at least four other people had been hurt. Victims included a 20-year-old man who was sent to Baltimore Washington Medical Center with a stab wound; a 19-year-old man and 20-year-old man were both sent to Howard County General Hospital with stab wounds; and a 16-year-old boy was sent to Baltimore Washington Medical Center after being struck in the upper body by an unknown object.

None of the injuries were life-threatening, police said.

An initial investigation revealed that the violence began with an altercation behind the house on Citadel Drive where a graduation party was taking place.

The altercation then moved to the front of the house, and that’s where witnesses reported hearing gunshots, police said.

Police said they are looking for one male suspect in connection with the case, but did not have a detailed description of him.
