A Denver police officer has been arrested and jailed on suspicion of sexually assaulting a woman he had met last month while responding to a call at her home, the Denver Police Department said Saturday.

DPD announced in a news release that Johnny Leon-Alvarez, 29, was arrested after he was named as a suspect in the investigation of a sex assault reported early Friday. He has been a Denver police officer since 2018 and was suspended without pay after the arrest, the release said.

An arrest affidavit says Leon-Alvarez met the 27-year-old victim in December when he was among officers who responded to her home. She had called police “regarding an argument she had with her significant other.”

After meeting her, the affidavit says, Leon-Alvarez began contacting the woman.

“One of the officers who responded began texting her afterward to check on her,” the document says. “Over time the (texts) became flirty, until the previous evening (Thursday) when they arranged to go on a date.”

The woman told police that Leon-Alvarez took her to Dave & Busters, an arcade and restaurant, on Thursday night. She said she recalled drinking, and at midnight the officer drove her home, the affidavit says.

“She tried to say goodnight at the door,” the report says. “She did not remember how he ended up coming in the house.”

The affidavit says police were called to her home at 2:55 a.m. Friday, and it says the woman’s roommate corroborated some details of her report, including that the woman protested any physical activity.

Leon-Alvarez was booked into the Downtown Detention Center, with bail set at $50,000.
