Larsa Pippen told police she was "scared" of Scottie Pippen during an Oct. 4th argument at their home -- in which the NBA star broke his own cell phone out of frustration ... TMZ Sports has learned.
We broke the story ... cops responded to Pippen's Florida home twice this month -- right before Scottie filed for divorce -- and now we've obtained the police report from the second incident.
Cops arrived to the home in the middle of the day and found Larsa waiting outside the home.
"She stated they were having marital problems and that he raises his voice to her, yells at her and scares her," the report says.
