A 25-year-old Memphis-based rapper taken into custody at an Alabama nightclub early Sunday is a suspect in the gunfire at an Arkansas club that left 28 people injured.

Ricky Hampton, better known as Finese 2Tymes, and another suspect were arrested by the U.S. Marshals Gulf Coast Regional Fugitive Task Force, ATF and FBI at 1:15 a.m. at Side Effects at 400 Second Avenue North in Birmingham, said Chief Deputy U.S. Marshal Cliff LaBarge. Hampton was headlining a show at the club from 10 p.m. until 2 a.m., and was nabbed as he walking back into the club.

Hampton was sought on aggravated assault charges out of Forrest City, Arkansas and was also sought after the Saturday morning shooting a the Power Ultra Lounge, a two-story club not far from the State Capitol. Hampton was headlining that show as well.

U.S. Marshals and ATF said they launched a search for Hampton after the Saturday morning Arkansas club shooting. After Hampton's arrest was announced, Little Rock police reiterated via Twitter that Hampton was arrested on the Forest City warrant, and that "no arrests have been made in the mass shooting."

Authorities have said the club was packed with patrons around 2:30 a.m. when, as an M.C. was speaking into a microphone onstage during a lull in the music, the sound of gunfire erupted. About 30 shots rang out over 10 seconds as people screamed and ducked for cover.

Among those injured, 25 suffered gunshot wounds and three others had unrelated injuries. Police believe the gunfire erupted amid a dispute among clubgoers and that multiple people fired shots. "Some sort of dispute broke out between people inside," Little Rock Police Chief Kenton Buckner told reporters on Saturday.

The chief also told reporters that he found it "concerning" that an advertisement for the concert included a photograph of the headlining performer pointing a gun toward the camera. He said the artist had two warrants related to violence in other cities, according to The New York Times.

LaBarge said lawmen searching for Hampton had developed information that he was going to being in Birmingham. U.S. Marshals, ATF and FBI set up surveillance at several areas in the city, and were searching for a silver Mercedes they believed Hampton would be in.

Hampton and 25-year-old Kentrell Gwynn were both arrested without incident outside the Birmingham club, he said. Investigators recovered two handguns and an AK-47 from the Mercedes. ATF took possession of those weapons.

The rapper was staying at The Tutwiler hotel, and authorities carried out a search warrant there as well.

Hampton and Gwynn were taken to the Jefferson County Jail. Jail records show Hampton was booked in at 3:34 a.m. on a fugitive from justice warrant. Gwynn was still undergoing the booking process. They will be held without bond pending extradition to Arkansas.
