Denver police are investigating an incident in which an officer discharged his weapon near East 33rd Avenue and High Street and a woman was injured.

“Preliminary investigation determined the shot was unintentional,” police reported on Twitter Tuesday night.

In an interview with 7News on Tuesday night from behind a closed door, the woman, who asked not to be identified, said a police officer dropped his gun, and it went off.

She felt a pain on her jawline but did not know for sure what hit her.

According to Denver police, officers were attempting to serve a probation violation warrant Tuesday afternoon on Lorenzo Banks, 28, when the suspect fled on foot.

After a short foot-chase, Banks was tracked to a nearby apartment complex unit, where he knew at least one of the “multiple” people inside, police said.

One officer fired a single shot, and a woman inside the unit was hit by either a bullet, a fragment or debris, said Steve Warneke, a police spokesman.

The woman was taken to a hospital with “superficial” facial and neck injuries, police said.

She was released from the hospital at about 6:30 p.m. after treatment for minor wounds.

Banks is in custody, police said.

Banks has an extensive criminal history dating back to 2002, with arrests for drugs, domestic violence, kidnapping, extortion and possession of a weapon by a previous offender, according to Colorado Bureau of Investigation records.

Tuesday’s incident marks the second incident this year in which an officer fired his weapon.

On Jan. 14, police shot and killed Blas Leroux, 35, who used a hostage as a human shield in a convenience store, which he entered while pursued by police.

The Denver District Attorney cleared the officer who fired the shot in that case, agreeing that the hostage’s life was in immediate danger.
