7:25 AM PT -- 12/13 Turns out Ratray's GF decided to make a police report a day after the incident. We've obtained the report in which his girlfriend claims the actor got physical with her during the argument, strangling her and putting his hand over her mouth. She says she bit his hand, he punched her in the face and she escaped to a stairwell. She then got her stuff and left, waiting for the cops to arrive.
"Home Alone" star Devin Ratray -- who played Buzz McCallister in the flick -- had a spat with his girlfriend that got so bad ... someone called the cops to get things under control.
Law enforcement sources tell us they were called to a Hyatt near downtown OKC earlier this week for a domestic dispute between Ratray and his girlfriend.
Ratray's rep says the two got into a verbal argument, nothing physical, and things were so nasty the two broke up. The rep would not say what the argument was about.
Cops tell us things were sorted out once Devin and his gf decided to go their separate ways for the night -- she got a separate room -- and no one was arrested.
Of course, Ratray will live in classic Christmas movie infamy as Buzz, who tormented his little brother Kevin (played by Macaulay Culkin) for years to come. The actor recently revealed to People that there was a possible "Home Alone" reunion in the works ... but unclear if this hiccup will derail that project.
