As if stealing a package from someone's front steps isn't cruel enough, a porch pirate in St. Paul added an insulting "thank you" note for the package's rightful owner. 

"Two days ago Hilary was notified that a package was delivered to her home on the 800 block of Watson Avenue. When she got home from work at about 5 p.m., the package was missing, replaced with a thank you note from the porch pirate. Unbelievable," wrote St. Paul Police Department in a tweet. 

The note reads: "So just a quick little thank you for leaving me the opportunity of stealing your package very nice of you. Thank you."

The note is signed by "The new owner of your package." 

Police say they are doing what they can to find out who the culprit is, and in the meantime they have six helpful tips to avoid being victimized by porch pirates. 

1. Require a signature for delivery. 
2. Have your package delivered to a neighbor who is home. 
3. Have your packaged delivered to your work address. 
4. Have your package delivered to an Amazon locker. 
5. Have you package delivered to a neighborhood store. 
6. Utilize an app that allows packages to be delivered in your home or vehicle. 

"It’s bad enough that we have to worry about people stealing our packages. But now they're leaving thank you notes? Ugh," St. Paul PD added.
