A top Baltimore Police commander abruptly resigned Monday, leaving Police Commissioner Anthony W. Batts with several moves to make in order to replenish his top ranks. 

Lt. Col. Clifton McWhite, who was nearing the end of his 19th year on the force, resigned effectiveimmediately on Monday, the department announced in an evening news release. They cited "personal reasons."

"Lieutenant Colonel McWhite was a talented member of our team and his service to the agency will be missed," Batts said in a statement. He declined to comment when approached by a reporter Monday night at a public meeting.

McWhite was one of three "area commanders," a new position created by Batts last year. Each area commander oversees three police districts - McWhite oversaw the western, northwestern and southwestern districts - but the department currently has two vacancies following McWhite's resignation and the departure of Lt. Col. Dan Lioi.

Deputy Police Commissioner John Skinner, who oversees the investigations and intelligence bureau, has also announced his retirement. And the agency has been without a training director for more than a year after a shooting at an unauthorized training exercise in Baltimore County in 2013.

McWhite had served a number of roles in recent years - in 2010 he was named to oversee the section that includes the sex offense unit, to implement reforms after The Sun reported that the department had classified a high number of rape cases as "unfounded." McWhite went on to be the commander of the Western District, and also oversaw the newly constituted Special Enforcement Section.
