NORTHGLENN, Colo. -- The scene is not suspicious on Valentine's Day. A delivery man with a long stem rose box emerging from a van that says "Flower Delivery" on the side.

In reality, there’s nothing in the box and the delivery man has handcuffs on his belt.

Undercover Northglenn police officers spent Valentine's Day rounding up unsuspecting wanted fugitives who thought someone was sending them flowers.

"Hello there, Happy Valentine's Day," officer Matt Hindman said at a door.

The man who answered is wanted for failing to appear in court on a marijuana charge.

Hindman explained the flowers are expensive and his boss wants him to check IDs.

The man returned with his license and asked for a pen to sign for the delivery.

"Northglenn police undercover, OK? You've got a warrant for your arrest, OK?" Hindman said.

Instead of flowers the man, who police identified as Ronald Madden, received silver bracelets and a trip to jail.

Before being taken into custody Madden joked with officers about the phony Valentine.

"Honestly it didn't click with me until I heard, 'Northglenn police' and then he pulled out the badge and I thought, 'Damn you guys are good,'" Madden said.

Lt. Commander Jeremy Sloan of the Northglenn Police Department said there were no major problems during the operation. However, there have been times of concern when flowers arrive unexpectedly.

"We talk to a significant other, or the husband, or wife who didn't send them, and sometimes they're a little suspicous about where they're coming from," Sloan said.
