One man was shot in the shoulder in the parking lot of Car Stereo Warehouse on Independence Boulevard late Wednesday afternoon. Bullets shattered a window of the store and also hit the tour bus of rapper Waka Flocka Flame, Charlotte-Mecklenburg police said.

"Everybody was ducking," said Al Armstead, who was inside the store at the time. "They were scared, frantic, panicking, knocking stuff over and bumping into each other and everything. It was crazy. It was chaotic."

A witness said he heard at least 10 gunshots.

Investigators said they think the target may have been Waka Flocka, whose real name is Juaquin Malphers.

"Somebody so high-profile in the pop culture world -- I'm sure that's exactly what they're looking at," said police spokesman Rob Tufano.

Malphers was having a stereo installed on the tour bus when the shooting happened. Store employee Habib Rahman said the rapper and his bodyguard were on the tour bus with two store employees, installing the sound system, when the shooting started. Two vehicles pulled up and people inside started firing, Rahman said.

He said the bodyguard started firing back and the two drivers then left.

Rahman said he had just walked into the store when the shots began.

“(I was) scared,” Rahman said. “Because I saw the bullet come in from the glass inside the store. The glass splashed everywhere, but everything happened so quickly, we didn’t even know what to do.”

A friend drove the wounded man, Josh Johnson, to a local hospital after the shooting, police said.

"We was chilling, everything was fine, and then it got crazy," Johnson said.

Johnson denied any involvement in the shooting.

"I'm no friends with (Waka Flocka)," said Johnson. "I'm a friend of Jesus."

Four people were questioned by police, including Waka Flocka and his brother, investigators said. The rapper and his brother were both released around midnight.

No arrests have been made.

Police are looking for an older model, low-riding white Land Rover with tinted windows and a newer model white Dodge Charger with custom wheels.
