An emergency alert meant for a small section of Denver's Ruby Hill neighborhood was accidentally sent to the entire city on Saturday afternoon, police officials said. Officers responded to an armed robbery and issued a shelter-in-place order for a one-block radius, but a follow-up alert to lift the order was mistakenly sent citywide.

Why it matters

This is the second time in recent months that Denver police have accidentally sent a citywide emergency alert, raising concerns about the reliability of the city's public safety notification system and the potential for confusion and panic among residents.

The details

According to police spokesperson Siena Riley, officers responded to an armed robbery near the intersection of West Gunnison Drive and South Zuni Street at 1:04 p.m. and issued a shelter-in-place order for a one-block radius. Police arrested two suspects and sent a follow-up alert to lift the shelter-in-place at 1:50 p.m., but this alert was accidentally sent to the entire city instead of just the affected neighborhood.

  • The armed robbery occurred at 1:04 p.m. on Saturday, April 18, 2026.
  • The shelter-in-place order was issued at 1:04 p.m. and lifted at 1:50 p.m. on the same day.
