A New York City resident’s day at a wellness clinic ended in a fatal tragedy over the weekend.

On Monday, the New York City Police Department stated that a 27-year-old woman died Sunday afternoon after she received an “anti-aging therapy” at the Bereshit Lifestyle Center in the Bronx.

The NYPD has since charged and arrested the clinic’s professed doctor, Luis Rojas Cabrera, over the woman’s death, which has yet to be fully investigated, police said.

“The New York City Office of Chief Medical Examiner will determine the cause of death and the investigation remains ongoing,” the NYPD said in a statement provided to Gizmodo.

An unlicensed doctor? On Sunday afternoon, police responded to a 911 call at the New York-Presbyterian Allen Hospital concerning the woman, who has not been identified by the NYPD.

Upon arrival, they were told by hospital staff that the woman had been transported unconscious and unresponsive to the hospital from the Bereshit Lifestyle Center.
