The British expat who had a dead baby turtle inside her vagina may have been a victim of a sexual assault, police said.

The 26-year-old woman, who lives on Tenerife in the Canary Islands, had no idea a Chinese three-keeled pond turtle was lodged inside her when she showed up at El Mojon hospital in Arona complaining of abdominal pain, Spanish outlet El PaÍs reported.

When doctors discovered the dead pet turtle — which caused a “serious infection” in her genitals — they called police last Saturday afternoon, fearing she had been abused, ABC reported.

The unnamed woman told local police she was out partying with a group of British pals Thursday night in the area of Fañabé beach a few days earlier, but doesn’t remember what happened that night, according to El Pais.

She then started feeling sick over the next few days before going to the hospital.

The woman insisted she did not want authorities to pursue the strange incident further, and police have halted their investigation pending new information.

“We are not actively investigating this matter because the woman declined to give a statement,” a police source told The Sun.

Though initial reports said the reptile was a tortoise, researchers confirmed is was a freshwater Chinese pond turtle, which are sold worldwide in pet stores and can reach up to 12 inches in length, El Pais reported.

Researchers at first believed the creature was a loggerhead sea turtle because they are indigenous to the Canary Islands archipelago.
