Two people are dead and eight others are injured following a shooting inside of a crowded South Carolina nightclub in the early hours of Sunday, authorities said.

A deputy and a trainee were passing Greenvilles Lavish Lounge just before 2 a.m., following an unrelated call in the area, when a commotion and the sound of gunshots caught their attention, Greenville County Sheriff Hobart Lewis said at an early morning press conference.

They heard more gunshots and called for backup before entering the club to locate the shooter. Inside, authorities found a lot of shell casings and blood, Lewis said.

At least two suspects remained wanted as of late Sunday morning, Lt. Jimmy Bolt with the Greenville County Sheriffs Office told HuffPost.

We do have some suspect information but its not a lot at this time, Lewis said at the earlier press conference, later adding that police suspect that the incident was gang-related.
