Arrests appear imminent in the rape of six Spanish tourists near Acapulco on Feb. 4, according to an official with Mexico's foreign ministry.
The six women were assaulted by five masked gunmen who barged into a rented beach bungalow in the middle of the night in Playa Encantada on the outskirts of Acapulco.
The victims are under the protection of Mexican authorities, who are pursuing strong leads in the case.
Acapulco's reputation as a choice resort destination has suffered in recent years due to upticks in drug-related violence, although none to date has targeted tourists.
Officials investigating the rapes have not tied the incident to cartel activity, however.
The recent U.S. State Department warning, issued on Nov. 20, recommended that travelers defer nonessential travel to areas outside Acapulco's popular beach areas. Follow Gay Nagle Myers on Twitter @gnmtravelweekly.
