Police arrested O.J. Simpson on Sunday, saying he was part of an armed group who burst into a Las Vegas hotel room and snatched sports memorabilia that documented his own sports career, long ago eclipsed by scandal.

The arrest starts a new legal odyssey for Simpson, the fallen football star who more than a decade ago in 1995 was acquitted of the slayings of his ex-wife and a friend, and opens the possibility he could spend decades behind bars.
