Sheriff’s deputies had an unusual suspect in the back of their patrol squad car this week in Imperial Beach, San Diego, California.

Let’s just say fingerprinting him could be tough.

A sea lion pup wandered away from the shoreline on Wednesday and waddled five blocks to Mar Vista High School. School staff called in San Diego County sheriff’s deputies to “investigate.”

Deputies detained the little guy, or put him in the back of the patrol car. Animal Control officers and SeaWorld workers arrived soon after to tend to the pup.

In a news release, sheriff’s deputies jokingly described attempting to figure out the sea lion’s motive.

“While deputy sheriffs attempted to interview him as to his activities, he clammed up and requested his lawyer,” the news release said.

On a serious note, an increasing number of sea lion pups, in search of food, are washing up on California's shores and scientists have said they don't know the remedy.
