HELSINKI — Finnish police have released two members of Cuba's national men's volleyball team but are holding six others on suspicion of aggravated rape, an investigator said Monday.

Police will request that a regional court on Tuesday order the six men to be remanded in custody to continue the investigation before any possible charges, said Joni Lansipuro, the Central Finland Police Department officer in charge of the investigation.

"We have made considerable progress in our investigation and have various pieces of evidence and relevant factors that support our suspicions," Lansipuro said. "We propose [to the court] that they be held in custody."

The eight men were detained over the weekend in Tampere after local police on Saturday morning received a report that a woman had been raped at a hotel in the city, 105 miles north of Helsinki. The Cuban team was in the city participating in the Volleyball World League tournament.

The Cuban Volleyball Association acknowledged the arrests in a statement Monday night. It said the Finnish investigation was continuing, but added that "early information implicates them in acts that are totally removed from discipline, the sense of honor and respect that govern our sport and society." The statement did not indicate whether the rest of the team had returned to Cuba.

Police declined to give further information pending the outcome of the investigation, except to say that the alleged victim and suspects were adults.
