Detroit ? For anyone keeping score, the leader of the nation’s 11th-largest city now faces 10 felony charges in two separate cases.

Mayor Kwame Kilpatrick was charged Friday with assaulting two investigators who were trying to deliver a subpoena to the mayor’s friend last month. The two felony counts carry a maximum penalty of two years in prison and a fine of $2,000.

Kilpatrick spent Thursday night in jail after violating bond conditions in the other case against him. He is accused along with a former top aide of perjury and other charges over their testimony in a lawsuit.
