Former employee arrested after threats against Denver Health paramedics prompt brief lockdown

Matthew Mann accused of stalking, harassment

DENVER - Denver police have arrested a former employee accused of threatening paramedics at Denver Health Medical Center on Thursday morning, causing a brief lockdown at the hospital.

Matthew Mann, 38, was arrested in the afternoon at the Denver Police Department for investigation of felony stalking and misdemeanor harassment, police said.

Police say they were called to Denver Health just before 7 a.m. about a former employee who had made possible threats against staff.

As a precaution, the Denver Health campus was placed on "modified" lockdown for about 90 minutes.

A modified lockdown meant that the hospital remained open to the public, but no one was allowed in or out of the building without identification. The emergency department remained open.

The lockdown was ordered around 11:30 a.m. and lifted just after 1 p.m. 

Officials would not release details about the threats but an internal Denver Health memo obtained by 7NEWS detailed that a former employee made  "real and credible threats" against the paramedics division and its command staff.

The memo identified Mann as the person making the threat and said he is a former employee who should be considered armed and dangerous.
