Kiefer Sutherland was released from jail early Monday after serving 48 days on a drunken-driving charge, police said.

The actor was ushered out a back door and into a waiting car at 12:05 a.m. to avoid the media near the Glendale, Calif., jail's main entrance, officer John Balian said.

Sutherland spent most of his jail sentence by himself, interacting with fellow prisoners only when he was on the way to the laundry room where he worked cleaning sheets, pillowcases and blankets, Balian said.
