After Spencer Pratt insisted in a dubious missive to TMZ that he'd been apprehended south of the border, legal paperwork now apparently proves that he was indeed arrested in Costa Rica over the weekend, as he was making his way back to the U.S.

His crime? Felony possession of a firearm.

Before news even reached the States, Heidi Montag's estranged hubby reached out to TMZ earlier today with the following statement:

"As part of my spiritual cleansing I've spent the last week living alone in the jungle, reflecting on my past transgressions, and working to become a better person. I had to live off the land, and hunt to survive. As I departed the country this morning to continue my spiritual journey, I mistakenly brought my hunting weapons to the airport. It was an honest mistake, and they sent me on my way."
