HOUSTON – A Houston janitor with sexually transmitted diseases was arrested for allegedly urinating into a medical practice’s drinking water and water bottles, according to media reports.

Diaz, who worked at the company for 20 years, has been charged with aggravated assault with a deadly weapon, according to KPRC, KSAT’s sister station in Houston.

Houston police said a woman employed at a doctor’s office noticed sour-tasting water from a 5-gallon water dispenser on Aug. 30. The water dispenser was placed in a common area and was used by staff and others.

The woman stopped drinking water from the dispenser and brought a personal water bottle to use.

In late September, the woman left her bottle, which was half filled with water, on her desk. When she drank water from it over the next day or so, she noticed that the water had a bad taste and smell, according to documents.

She threw away the water bottle and purchased a new one. Police said one day, she noticed a yellow-colored liquid inside her water bottle.

Believing it was urine, the employees had the liquid tested and the results confirmed it was urine, documents state.

Police said another coworker said she had a similar experience.

The woman purchased a security camera and attached it to her computer. She told police that footage showed the janitor, identified as Diaz, place his penis inside her bottle and urinate in it, documents state.

He repeated the act twice over a few days, police said.

Officers questioned Diaz, who admitted to the act and said he had a “sickness,” KPRC reported.

He said he didn’t know how many times he urinated in the medical practice’s drinking supply.

KPRC reported that Diaz tested positive for two sexually transmitted diseases, including one that’s incurable.

The woman who recorded Diaz later tested positive for the incurable disease, police said.

The name of the disease wasn’t released, but doctors said it may weaken the immune system and be life-threatening, KPRC reported.

KHOU reported that 11 other people are being tested for sexually transmitted diseases.
