As serious mental health calls to police and social service groups rise, law-enforcement agencies are investing in extra training to help officers untangle situations ranging from erratic behavior to drug overdoses to suicide attempts.

Anoka and Dakota counties have seen their mental health 911 calls, including suicides and attempts, increase by more than 25 percent in the past two years, to more than 2,000 in Anoka and about 1,730 in Dakota. Some police departments, including those in Eagan, Hastings, Burnsville and Buffalo, have increased officer training to better handle such calls or have plans to do so.
