The top Baltimore city police officer suspended following Freddie Gray's death was hospitalized in April 2012 following concerns about his mental health, according to records from a sheriff's department and court obtained by The Associated Press.

Worries about the lieutenant — originally raised by a fellow Baltimore police officer who is the mother of his child — led Carroll County, Md., deputies to confiscate his guns and contact high-ranking police officials, the report says.

The lieutenant, who initially pursued Gray on a Baltimore street when Gray fled after the lieutenant made eye contact April 12, declared three years ago that he "could not continue to go on like this" and threatened to commit an act that was censored in the public version of a report obtained by the AP from the Carroll County, Maryland, Sheriff's Office. The lieutenant lived in the county, about 35 miles northwest of Baltimore.

In the Freddie Gray case, the lieutenant faces charges of involuntary manslaughter, second-degree assault and misconduct in office.
