Many thefts reported in town that day

The package was stolen from Gardner resident Matt Elsevier, who at first believed the thief was an actual Amazon delivery employee, according to local station WCVB-TV.

"He walked in carrying a package with his phone. You know, he made it look (legitimate) like he was actually going to drop off a package," Elsevier told the station. "As soon as I saw the footage, I made a call to the police and filed a report. I sent them all the security footage that I had."

Gardner police Det. Lt. Matt Arsenault said Elsevier's home was one of many thefts that day, WCVB-TV reported.

Arsenault urged residents to consider having their packages delivered to other more secure locations, like the Post Office, a UPS Store or a nearby Amazon locker.
