SOUTH BEND, Ind. (AP) _ A naked man ran through the streets, scuffled for a woman's car keys and climbed a tree, then grabbed a police officer's gun and shot at other police, who returned fire and wounded him, authorities said.

The man, identified by police as Thomas Joseph Leen, 22, of Dayton, Ohio, was in stable condition Sunday in the intensive care unit of Memorial Hospital.

Leen was expected to be charged Monday with attempted murder, said police detective Tom Tremerry.

Members of Leen's family, who live in Minnesota, said Leen had been under psychiatric care since last year, said Tremerry, who would not discuss details.

Leen allegedly broke into and vandalized a home Saturday afternoon and removed his clothes there, said police Lt. Richard Kilgore.

Leen then reportedly jumped onto the back of a moving van, and climbed on top of a parked car and lowered himself inside through the sunroof, Kilgore said.

The owner of the car saw him and ran to the vehicle, and he beat her during a scuffle for the keys, which were inside. She suffered minor injuries but did not seek treatment.

When police arrived, Leen jumped out of the car and ran. Police said he climbed a tree and, when an officer tried to get him to come down, jumped on the officer and grabbed his revolver.

A second officer arrived, pulled his revolver and told Leen to drop the weapon. At that point, Kilgore said, Leen began firing at the officers, with one bullet going through a window of a nearby house.

Leen was shot several times.

Police said they believed Leen was a student at the University of Dayton who was visiting a friend in South Bend.
