Smithfield, Virginia police are using the popular Pokemon Go game to lure gullible criminals into the station for arrest, and the idea is quickly spreading to other police agencies.

“The rarest Pokemon of all has been spotted in the Smithfield Police Department processing room: Ditto!” the Smithfield Police Department posted to its Facebook page about a week ago.

“Since it so rare we can only allow a limited number of people in the building to capture it. We put the mainframe computer in the basement to work and came up with a list of random citizens eligible for this rare opportunity,” the post read. “If your name is on the list below, you are one of the lucky folks invited to come to the Police Department for the capture!”

What police neglected to omit is that the eight people listed by name in the post are actually the ones that will be captured, Sgt. Bryan Miller, a road patrolman who manages the department’s Facebook page, told the Virginia Pilot.

He said the folks listed are wanted on outstanding warrants for alleged crimes ranging from trespassing to grand larceny.

“He doesn’t expect to clear Smithfield’s list of outstanding warrants, he said, but he also wouldn’t turn away any of the listed ‘players’ if they’re lured in by the purple Pokemon,” according to the news site. “He’s got some handcuffs waiting for them in the processing room …”

“I have a sense of humor,” Miller said. “I had no idea it was going to be this big.”

Smith, who said he got the idea from another police department, described himself a Pokemon Go fan, but said he’s not “hardcore.”

“What can I do to get on this list?” Austin Pittman posted.

“Commit a felony, that’s a great start,” Michael Harmon responded.

The Guardian pointed out that police in Manchester, New Hampshire used the same tactic about two weeks ago, though it’s unclear whether either department has actually apprehended any wanted criminals using the posts.

“Attention all area #PokemonGo players: we have recently found out that there is a #Charizard in our booking area. With the Charizard being such a rare character, we are only inviting a specific number of people. If your name appears on the following list you are one of the lucky ones,” Manchester police posted to Facebook.

“Come down to the station to capture Charizard. Hurry before the Charizard leaves!”

The Manchester post linked to the department’s list of wanted persons.

According to The Guardian:

While it’s unlikely any of the “lucky” few named in either post will actually come forward, police have actually already caught one criminal thanks to Pokémon Go.

A man in Detroit cycled to his local police station, which was also a gym in the game, to play. Unfortunately for him, police officers recognised him as someone with an arrest warrant.
