MINNEAPOLIS — Police were called when a naked patient tackled the director of a Minneapolis mental facility and tried to sexually assault her.

KSTP-TV reports the man is in his 30s and lives at the facility. Police say he burst into a staff meeting Tuesday and threw the director to the floor.

When co-workers were unable to restrain the man, they called police. It took four officers to handcuff the man. He was taken to a hospital for observation.
