The Northglenn officers used a van with a sign saying "Flower Delivery" and knocked on doors bearing a long-stem rose box to net their quarry.
"Hello there. Happy Valentine's Day," Officer Matt Hindman told one man wanted in this northern Denver suburb for failing to appear in court on a marijuana possession charge.
The man asked for a pen to sign for delivery. Hindman announced: "Northglenn police undercover, OK? You've got a warrant for your arrest, OK?"
Handcuffed, the man, identified by police as Ronald Madden, chuckled as he told Channel 7 News he'd been fooled.
"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.
