ACAPULCO, Mexico (AP) -- Authorities have information they hope will lead them to the gang of armed, masked men who raped six Spanish tourists in the Mexican resort of Acapulco, the attorney general in the southern state of Guerrero said.
The vicious, hours-long attack at a beach home on the outskirts of Acapulco before dawn Monday was the latest chapter of violence that has tarnished the once-glamorous Pacific coast resort celebrated in Frank Sinatra songs and Elvis Presley movies.
"Fortunately we have strong evidence to lead us to those responsible for this reprehensible act," Guerrero state Attorney General Martha Garzon Guzman told Mexico's Radio Formula on Monday.
The beach home on an idyllic stretch of coastline had been rented by six Spanish men, six Spanish women and a Mexican woman.
The attackers gained access to the house because two of the Spaniards were in the yard and apparently were forced to open the door, Acapulco Mayor Luis Walton told a news conference late Monday.
The five attackers burst into the house and held the group at gunpoint, he said. They tied up the six men with phone cords and bathing suit straps and then raped the six Spanish women. The Mexican woman was not raped.
Garzon said the Mexican woman begged the men not to rape her and the assailants told her they would spare her because she is Mexican.
The attack began on Monday about two hours after midnight and the victims were only able to report the crime five hours later, at nearly 7 a.m.
"This is a regrettable situation, and of course it is going to damage Acapulco," Walton said.
The once-glittering resort that attracted movie stars and celebrities in the 1950s and 60s has already been battered by years of drug gang killings and extortions, but except for very few incidents, the violence has not touched tourists.
Walton said he believed, but wasn't sure, that the assailants in Monday's attack didn't belong to a drug gang. Garzon said witness descriptions of the attackers were more difficult to obtain because they wore masks.
"From what the attorney general has told me, I don't think this was organized crime," Walton said. "But that will have to be investigated, we don't know."
Mexico's Foreign Relations Department issued a statement saying it regretted the attack.
"Up to now, the investigations are being carried out by local authorities and they will be the ones to provide information," the statement said.
In Mexico, it's up to local authorities to determine if organized crime is behind an attack, and, if so, turn the case over to federal authorities.
Security and drug analyst Jorge Chabat said that, after years of drug gang activity in Acapulco, the distinction may be merely semantic.
"At this point, the line between common and organized crime is very tenuous, there are a lot of these gangs that take advantage of the unsafe situation that currently exists, they know the government can't keep up," Chabat said. "
The Spanish Embassy in Mexico City said the victims were receiving consular assistance.
The victims were "psychologically affected" by the attack and received treatment, the mayor said.
Spain's Foreign Ministry had already issued a travelers advisory on its website for Acapulco before the Monday attack, listing the resort as one of Mexico's "risk zone," though not the worst.
"In Acapulco, organized crime gangs have carried out violence, though up to now that has not affected tourists or the areas they visit," the advisory states. "At any rate, heightened caution is advised."
The attack came just three days after a pair of Mexican tourists returning from a beach east of Acapulco were shot at and slightly wounded by members of a masked rural self-defense squad that has set up roadblocks in areas north of Acapulco, to defend their communities against drug gang violence.
The vigilantes say the Mexican tourists failed to stop at their improvised roadblock.
Walton said the city was already contemplating ways to revive the city's image.
"We have to look at an advertising campaign to say that not everything in Acapulco is like that," Walton said. "This happens everywhere in the world, not just in Acapulco or in Mexico."
The attack came just four days after Tourism Secretary Claudia Ruiz Massieu visited the International Tourism Fair held in Madrid to launch a "promotional offensive" depicting Mexico as a safe and attractive destination.
"This is Mexico's moment," Massieu said, describing it as "a safe country."
Acapulco is the granddaddy of Mexican resorts. Elizabeth Taylor was married there, John F. and Jackie Kennedy came on their honeymoon, and Howard Hughes spent his later years hiding out in a suite at the Princess Hotel, a pyramid-shaped icon in the exclusive Punta Diamante, or Diamond Point, zone.
Beheadings and drug gang shootouts, some on the city's main seaside boulevard, became more frequent after 2006, as gangs fought for control of the city's drug and extortion business.
