Scores of brutality lawsuits are filed against the Philadelphia Police Department every year. But it’s unusual for an officer, a sergeant no less, to make those charges.

In a suit filed Monday, Sgt. Brandon Ruff did just that.

Ruff claims he was roughed up by seven officers from the 35th District when he attempted to anonymously turn in three handguns at the precinct. Ruff, who says he suffered two sprained wrists and two sprained shoulders in the fracas, filed suit in U.S. District Court in Philadelphia.

Ruff, an eight-year veteran assigned to the 16th precinct, said the acts of the 35th District officers “were committed willfully, wantonly, maliciously, intentionally, outrageously, deliberately and/or by conduct so egregious as to shock the conscience.”
