Scottie Pippen's Wife told Cops 'HE SCARES ME'

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.

Cops say they found Scottie inside the house and he acknowledged an argument -- saying, "he was upset and did break the screen on his phone in frustration."

Scottie agreed to leave the house to let things calm down. Larsa told police she would be talking to an attorney. Neither party was arrested.

Once again, there were NO allegations of domestic violence -- just another screaming match ... same kinda thing from the first incident on October 2nd.

As we previously reported, Scottie had been unhappy with his wife's relationship with Future -- though our Larsa sources claim their relationship is just "casual."
