The Institutional Revolutionary Party, or PRI, candidate for mayor of Apaxtla de Castrejon, a town in the southern Mexican state of Guerrero, reappeared two days after reportedly being abducted by gunmen, the state Attorney General's Office said.

Marcelo Avila Velazquez's relatives did not file a kidnapping complaint after the candidate was pulled from his home Monday by three armed men, although the PRI's State Administrative Committee said he had been taken away against his will and demanded an investigation.

The state AG's office, for its part, said Avila reappeared Wednesday but did not say the time or place and also did not indicate whether his disappearance had been ruled a kidnapping or if any ransom had been paid.

It merely said that Avila "is fine generally speaking," although he had suffered some "bumps and bruises" and a "nervous crisis" and had been taken outside the state for a more thorough medical exam.

The PRI said in a statement Tuesday that Avila, candidate for mayor of the town of about 7,000 people in this weekend's general elections, was abducted on Monday afternoon.

At least 15 PRI candidates in the July 1 elections have received threats in the state's conflict zones and there are "candidates who have not campaigned" because of this, the PRI's leader in Guerrero, Cuauhtemoc Salgado, said in a press conference this week in Chilpancingo, the state capital.

"They have received messages on their cell phones and in calls," the state party leader said, without revealing if he suspected who was behind the threats.

"We have a critical situation, there is psychosis among the citizenry," Salgado said.

Avila is among the candidates who got threats, according to Salgado, who would not reveal the names of the other 14 for "security" reasons.

The PRI is in the opposition in Guerrero and nationally although it is poised to take back the presidency with Enrique Peña Nieto as its standard-bearer.

Apaxtla is in an area of Guerrero where gunmen working for drug cartels have staged a number of attacks.

The state's northern and Tierra Caliente regions have been especially affected by drug-related violence.

Rafael Ariza, a PRD politician, was abducted last week in the city of Coyuca de Benitez and the kidnappers have demanded the payment of ransom.

Guerrero Gov. Angel Aguirre launched a security operation last year with the support of the federal government to step up security in areas frequented by foreign and domestic tourists, such as the Pacific resort city of Acapulco.

"Operation Safe Guerrero" was launched on Oct. 6 in an effort to reduce the soaring crime rate in the state.

Separately, lawmakers in Veracruz state voted to remove the mayor of the town of Chinameca from office after he was arrested in April along with a group of suspected gunmen linked to the Los Zetas drug cartel, considered Mexico's most violent criminal organization.

The state lawmakers determined there was evidence linking Martin Padua to organized crime and named Lazaro Francisco Luna to replace him.

Padua, a member of the ruling National Action Party, or PAN, was detained by army soldiers on April 17 along with five suspected Zetas members who hours earlier had clashed with state police and army soldiers in the southern part of Veracruz state.

Padua, who is currently being held in a lockup in Mexico City, is under investigation by the federal Attorney General's Office for links to organized crime. EFE
