Pitbull cited safety problems when he declined to take the stage for a concert in the eastern Bolivian city of Santa Cruz, but media accounts Wednesday said he made the decision after two of the promoter's employees were arrested.

The Cuban-American rapper said on Twitter that he while felt bad about canceling Tuesday night's show, his decision was motivated by concern for the safety of his fans.

Santa Cruz's police chief, Col. Lily Cortez, told reporters that two people, one of them a foreign national, were arrested at the venue with a loaded gun, a baseball bat and a forged Bolivian police credential.

Released within hours, the two men were employees of the company that organized the concert, media outlets said.

The promoters promised to reschedule the concert, but did not set a date, and the roughly 12,000 fans who came to Santa Cruz's Tahuichi stadium to see Pitbull perform did not hide their disappointment.

Pitbull's concert Wednesday night in La Paz will proceed as planned, promoter Boris Navarro said.
