Swedish family sues Miami Beach hotel after alleged pool assault

A Swedish family is suing the Radisson Resort Miami Beach for more than $15 million, saying a non-guest entered the pool area and sexually assaulted their 11-year-old daughter during a first-time vacation in South Florida. The case puts hotel duty of care front and center: not just what happened at the pool, but how a stranger got past access controls in a space meant to protect children.

The lawsuit, filed May 14 in Miami-Dade Circuit Court, says the alleged attack happened in October 2025, about two days into the family’s weeklong stay at the hotel on Collins Avenue at 43rd Street in Miami Beach. Police identified the accused man as Osvaldo Diaz, who was arrested Oct. 27, 2025 on charges including lewd and lascivious battery on a child and burglary with assault or battery. Authorities said Diaz was not a registered guest at the hotel.

According to the family’s lawyers and local reporting, the property had a key-card system in place, yet Diaz allegedly entered the pool area anyway. The suit claims the hotel failed to provide adequate security and did not use reasonable access-control measures. That question now looms over the case: whether a major beachfront hotel can claim child-safety precautions were in place when an outsider allegedly moved freely into a family pool area.

The family was vacationing in South Florida for the first time with their three daughters, ages 19, 14 and 11. Their attorney, Justin Shapiro, said the hotel had no visible security and argued that anyone could have followed guests into the pool area from the beach or lobby. WSVN reported that the girl was swimming when the suspect allegedly grabbed her buttocks, followed her underwater and touched her between the legs. CBS Miami also reported that Diaz allegedly fled through a neighboring hotel before being found showering there and taken into custody.

The girl’s father said his daughter is still traumatized and sleeps in her parents’ room more often. Her mother said the child has not been the same since the incident. The hotel owners had not publicly responded in the available reporting, leaving the lawsuit to raise broader questions about whether family-focused resorts are doing enough to secure pools, screen entrants and protect children from non-guests who can exploit gaps in hotel security.
