TMZ Sports has obtained the police report from Tre Mason's encounter with police on July 23rd -- which details strange behavior, a violent outburst and more evidence of mental illness.

According to the report, filed by the Palm Beach County Sheriff's Office ... cops say Tre's mother had called because her son was "acting unusual and making irrational statements."
When Tre saw the cops, he threatened to call the White House and have them all fired -- and made bizarre statements about Al Qaeda ... so says the report.
Upon inspection, cops noticed a hole that had been punched in the wall of Tre's bedroom and a broken vase and lamp. Tre also had a cut on his hand, but was refusing medical attention.

Mason was a no-show at L.A. Rams training camp -- and head coach Jeff Fisher says the running back hasn't spoken with anyone in the organization since 2015.
It now seems pretty clear why ...
