A man was shot at a party in Crownsville early Saturday, but details on the incident remain sketchy, Anne Arundel County Police said.

Officers went to the Anne Arundel Medical Center emergency room around 3:15 a.m. Saturday to meet the victim and his female friend, both 20, police said. They told police they were at a party at the Summerhill Trailer Park and went outside.

There, they heard a loud bang, and quickly left the party along with everyone else, police said. The man told police he realized he had been shot when his back started hurting on the way home. They drove to the hospital.

Police said details about the incident are unclear after talking to the victim and his friend, and they are not releasing more information about the investigation.
