"You would never believe it," Deputy Chief Mark Coil told the station. "Just when you think after 25 years in the business you've seen it all, you get a call from a shift commander telling you that we have corralled a pig."

Coil said the whole thing started when police received a 911 call around 7 p.m. Thursday from a woman who said there was a pig on the loose and she didn't know what to do.

According to reports, the woman was doing yard work when the pig came barreling toward her. It then chased her into the front yard before getting distracted by a decorative ball.

"Officers responded and were able to detain the pig and get him in the back seat of the patrol car," said Coil. "Realistically, the pig didn't give us much trouble. We used a dog pole that we would use for a dog at large and were able to corral the pig and take the pig into custody without any problems whatsoever."

The real problem occurred afterward -- when officers got the pig back to the station.

"Well, lets say the pig either out of excitement or otherwise felt the need to use the back seat of our patrol car as a bathroom," Coil told the station.

As officers were pondering their next step, they received a call from its owner.

"He called and said 'Hey, I think you're looking for a pig and it may be mine,'" said Coil.

According to a message posted on the department's Facebook page, the owner showed up at the station to "bring home the bacon," and cleaned out the police car while he was there.

A photo of the pig smiling in the back of the cop car has since gone viral.

"I think he feels that he got the last laugh," said Coil.
