UPDATE | Governor lifts state of emergency for Baltimore

BALTIMORE (AP) — The mayor called on federal investigators today to look into whether this city's beleaguered police department uses a pattern of excessive force or discriminatory policing.

Mayor Stephanie Rawlings-Blake said even though complaints of excessive force and lawsuits alleging misconduct are down over the last few years, "we all know that Baltimore continues to have a fractured relationship between the police and the community."

Baltimore saw days of unrest after Freddie Gray, a black man, was taken into custody and suffered critical injuries. He died a week later. Protesters threw bottles and bricks at police during a riot on April 27, injuring nearly 100 officers. More than 200 people were arrested, and about 170 cars and 250 businesses were burned.

Maryland Gov. Larry Hogan declared a state of emergency and called in 3,000 National Guardsmen and 1,000 officers from around the state and country. Hogan rescinded the state of emergency today and said all the troops and state police had been pulled out. He said $20 million from state's Rainy Day Fund will help pay for last week's response.

He said the federal investigation was "probably a step in the right direction."
