Venezuelan authorities have arrested an allegedly heavily armed American citizen on Tuesday, accusing him of being a "mercenary," according to multiple news reports.

Todd Michael Leininger, 32-year-old U.S. citizen from Florida, is accused of attempted murder and arms dealing. Venezuelan authorities arrested Leininger after a raid on his house in San Cristobal, the capital of the state of Tachira, close to the Colombian border, where they found three rifles, two handguns, ammunition and eight military camouflage uniforms, according to the Miami Herald.

The police also found a document identifying Leininger as a captain in a U.S. police or military unit, said Tachira's governor Jose Vielma, and suspects him of being a U.S. agent, according to the Spanish news agency EFE.

The local government of Tachira tweeted two pictures of Leininger alleged arsenal, calling him a "mercenary."

The authorities suspect Leininger entered Venezuela two months ago, and that he might have been involved in the violent clashes San Cristobal, according to the local TV TeleSUR.

On Wednesday, Venezuela's Supreme Court confirmed that the local criminal court in the state of Tachira has ordered Leininger to remain in custody, according to the local newspaper El Universal. Leininger is accused of shooting and wounding a Venezuelan citizen named Jorge Santos Sandoval. Vivian Virginia Arreaza Sandoval, who appears to be Leininger's wife, has also been arrested and ordered to remain in custody.

UPDATE, April 24, 2:48 p.m.: A U.S. State Department spokesperson told Mashable that they are aware of a U.S. citizen arrested in Venezuela, and that they are ready to "provide all appropriate consular services." But because of "privacy concerns," the spokesperson declined to comment any further.
