A US journalist has walked oblivious through a live broadcast, purportedly while playing augmented reality phone game, Pokémon Go.

Video shows 10News WTSP journalist Allison Kropff cross the screen in a few brisk strides before vanishing from view.

Her mistimed attempt, apparently to catch Pokémon, saw her walking directly in front of presenter Bobby Deskins while he was delivering a forecast for Florida.

“Got a Pokéman [sic]? She’s looking for Pokémon right now,” Deskins said, before bursting into laughter.

“You guys have got to be careful with these phones and this Pokémon.

"You're just walking around all over the place."

Ms Kropff posted video of the supposed on-screen gaffe to her Twitter account yesterday.

“That moment you realise you may be addicted to #PokémonGO,” she tweeted.

Ms Kropff is yet to confirm whether her distracted wandering through the studio was a deliberately staged stunt.

Pokémon Go made headlines following its release last week and meteoric rise in popularity, seemingly overnight.
