O.J. Simpson Arrested, Held Without Bail

O.J. Simpson was arrested Sunday and ordered to be held without bail in connection with an armed robbery involving sports memorabilia that took place Thursday night in a Las Vegas hotel.

The former football star, 60, has been charged with two counts of robbery with a deadly weapon, two more counts of assault with a deadly weapon and conspiracy to commit burglary with a firearm.

Authorities apprehended Simpson shortly after 11 a.m. in his room at the Palms Hotel in Las Vegas and brought him to a police office.

So what happened? TMZ has obtained an audio tape of Simpson's confrontation (follow link to hear it) with the memorabilia dealer that led to his arrest.

In it, you can hear someone say, "You, against the motherf*%king wall!"

The tape was recorded by Thomas Riccio, who co-owns auction house Universal Rarities. Riccio met up with O.J. Simpson just before the confrontation at the Palace Station Casino on Thursday night.

According to reports, Riccio was on hand to help O.J. Simpson prove some memorabilia being auctioned by Alfred Beardsley was ill-gotten.

Riccio says he believed Simpson was going to confront Beardsley to give him an ultimatum - hand over the goods or Simpson would call the cops.

Riccio turned his Olympus digital voice recorder on before the group came in the room - a group that included Simpson and four other men.

Almost immediately, O.J. Simpson went wild, hurling profanities at Beardsley and another memorabilia dealer, Bruce Fromong.

The confrontation lasts six minutes. It is graphic and telling. Simpson is clearly the ringleader. Simpson repeatedly says, "Think you can steal my $h!t and sell it?"
