Cops say they got a call on possible shots fired from inside an apartment early Saturday, and when they arrived ... they found Latimer and two other people inside -- one of whom had minor injuries unrelated to a gunshot. All of them were detained, but only Latimer was ultimately arrested. No other info is available at the moment.
Washington Redskins star Cody Latimer was hauled off to jail this weekend after cops say he was involved in assaulting someone and illegally using a firearm.

The wide receiver was arrested early Saturday morning just after midnight in Englewood, Colorado, where cops were summoned to an apartment complex Cody was at. It's unclear what led up to the arrest or why police were called -- but Cody was taken into custody.

He was booked on several charges ... assault in the second degree, illegal discharge of a firearm, prohibited use of a weapon, reckless endangerment and menacing. He was processed at the Douglas County Detention Facility -- and has reportedly already bailed out on a $25,000 bond.

The Redskins have responded to Latimer's arrest, saying ... "We are aware of the situation and have informed the NFL League Office. We will continue to gather more information and have no further comment at this time."

Cody's had a run-in with the law before in Colorado -- he was arrested in 2016 during a domestic disturbance call he made on his GF ... back when he was a Bronco. Later, it was revealed Cody was only taken in on an outstanding warrant for a failure to appear in court from a traffic ticket.
