A Pokemon Go player walked into a stranger's house in pursuit of monsters while playing the virtual reality game, it is reported.
When the man was questioned about the incident in Norwich, he told police it was because he was playing the app.
It was among 19 Pokemon-related incidents recorded by Norfolk Police in July and August of this year.
The data obtained by the BBC also included a motorist driving "erratically" while hunting for monsters and a man whose phone was snatched out of his hand while the offender distracted him by talking about the app.
Gamers have also been involved in robberies, driving offences and a mass brawl since the augmented reality game hit Britain's streets this summer.
As of August there were 290 Pokemon Go-related incidents recorded by police forces across England and Wales.
Pokemon Go uses a smartphone's GPS to create an augmented reality game in which players collect creatures known as Pokemon as they walk around the real world.
Gamers can visit locations known as Pokestops, which are usually local landmarks, where they can pick up free items to play the game.
