After 48 days behind bars, Kiefer Sutherland was released from incarceration Monday morning at a Glendale, Calif. jail.

The actor left at 12:05 a.m., according to jail spokesman John Balian.

"[Kiefer] looked like he was glad to be out," said Balian, who added that the actor was wearing a shirt and jeans when he left, and took home whatever personal belongings he originally brought with him.

Sutherland, 41, served his entire sentence for a second DUI conviction and for violating probation. He spent his birthday, Christmas and New Year's at the Los Angeles-area facility.

"Throughout his stay, he never griped, never complained," Balian previously said. "He never wanted preferential treatment from the get go, and we respect him for that."

Sutherland was housed alone in an 8 by 10 foot cell, but was not confined to it, having access to a larger day room with a TV.

The actor was only visited by his attorney. The 24 star did not include any family or friends on his visitor request list. (His doctor was the only other approved visitor).

Sutherland kept largely to himself, having scant contact with other inmates, Balian said.

The actor was also sentenced to five years probation, and must complete an 18-month alcohol education program and attend weekly therapy sessions for six months.
