It was one of the “Stranger Things” to happen on a police department’s Facebook page.

An Illinois man wanted on a drunk driving warrant agreed to turn himself in — but only when local police Photoshopped his mugshot on their official Facebook page to include a Halloween costume.

Brandon W. Conti, 25, was featured in the Kanakee County Sheriff Department’s popular “Warrant Wednesday” social media post this week. Conti was wanted for missing a Sept. 30 court appearance to review his DUI case, the Daily Journal reported.

Fugitives don’t usually chime in, but this time — just a day before Halloween — Conti did.

“I’m appalled,” Conti wrote in a comment that appears to have since been deleted, according to the Journal. “Where’s my costume?”

A short time later, the department featured a Photoshopped image of Conti in a sailor’s outfit, including a cap with one word, “Ahoy” — a nod to actor Joe Keery’s depiction of the character Steve Harrington in the popular Netflix series “Stranger Things.”

“Done! We held up our end of the bargain,” an officer replied. “Now, you do the right thing and ‘Sail’ yourself on in here and turn yourself in. Or, call us, and we’d be happy to provide you transportation.”

A clearly amused Conti replied with two laughing face emojis and a thumbs up.

“That’s awesome,” he wrote. “I’ll be there before noon please have the paperwork done and ready.”

“Did he turn himself in by noon like he said he would?” someone commented Thursday.

“Sure did,” Conti replied. “I’m a free man now.”

Bail was set at $3,000 and Conti needed to pay 10 percent, according to the outlet.
