Baltimore police have arrested a tutor they say assaulted a 7-year-old boy in school, leaving him hospitalized with significant injuries.

Spokesman T.J. Smith said at a news conference that 25-year-old Timothy Randall Korr of Baltimore was charged Wednesday with child abuse, assault and other offenses.

Smith said Baltimore police were called Monday by school police at City Springs Elementary/Middle School.

Officers met with the boy's family at Johns Hopkins Hospital. The boy's parents tell WBAL-TV that their son's injuries will require surgery.

Smith says school surveillance video shows Korr carrying the child and slamming him against a wall.

School officials said in a statement that Korr worked for Baltimore Curriculum Project, a contractor.

It could not be determined if Korr has a lawyer.
