Police say an armed man accused of trying to rob Pokemon Go players in Las Vegas before a shootout left him and a player injured now faces charges of conspiracy, robbery, battery and assault with a deadly weapon.

Authorities said Tuesday that 18-year-old Elvis Campos was taken to jail after being treated at the hospital for a gunshot wound to the back.

Campos was shot early Monday as he was demanding the possessions of six people at a park east of downtown as they were playing the popular smartphone game, which sends players to physical locations to "catch" virtual Pokemon characters.

The two sides exchanged fire after a player who has a concealed weapons permit drew his own gun.

A juvenile with Campos at the time also faces charges.
