Robberies, trespassing, even a body found.

The common thread: the new Pokémon Go app that’s poised to have more users than Twitter.

Here’s how it works. People wander around the real world and use their smartphone app to look for and collect virtual Pokémon characters at spots near their location.

It may sound strange, but it’s sweeping the nation, and prompting warnings from law enforcement.

Poké stops, like Kissaten Coffee Bar, are locations in the real world, marked in your in-game map, where you can nab items to help you capture Pokémon.

“It’s very popular,” said Honolulu resident Jon Wong. “Everybody except grandma is playing this. Maybe grandma is playing this.”

“My friend told me the other day, ‘Hey, did you hear about this new app?’ I said, no, I didn’t, so I downloaded it and started walking around and — a Pokémon just popped up!” said Honolulu resident Reece Hirano.

We stopped by a local web development company, Sudokrew. Project manager Matthew Tengasantos said, “I was looking up traffic online. Pokémon Go has reached active users, and is about to surpass Twitter.”

In five minutes at Kapiolani Park, KHON2 found five people who say they’re chasing Pokémon.

Gamers say it’s addicting. On Sunday night, Tengasantos stopped by Kapolei Public Library and the neighboring regional park.

“You can go to these stops, swipe them, get items. There’s easily 100 people there. It’s like, midnight. You’re seeing cops go by, going like, ‘What is going on here?’ and then everybody’s like, ‘Dude, you need to download this app!’ and then we get cops to jump in and play the game,” Tengasantos said.

“I have heard some folks, not here locally, but stories nationwide that they get robbed because they know people are looking at their phones and not aware of their surroundings, especially at night,” said Kent Salcedo, Sudokrew junior web developer.

But the popularity of the game raises safety concerns, which prompted the Honolulu Police Department to issue warnings that gamers and parents need to know.

Police officials say they want people to enjoy the game, but play it safe.

Never play the game while driving. It’s a $297 fine if you’re caught on your cell phone.

Stay in a group, and don’t go into unfamiliar or isolated areas, especially at night.

Lastly, don’t trespass or damage other people’s property.
