An angry Las Vegas judge doubled O.J. Simpson's bail to $250,000 Wednesday for violating terms of his original bail by attempting to contact a co-defendant in his armed robbery case.

Simpson, clad in jail attire, grimaced as the amount was announced and meekly acknowledged that he understood.

"I don't know Mr. Simpson what the heck you were thinking -- or maybe that's the problem -- you weren't," Clark County District Court Judge Jackie Glass said as she lectured Simpson. "I don't know if it's just arrogance. I don't know if it's ignorance. But you've been locked up at the Clark County Detention Center since Friday because of arrogance or ignorance -- or both."

The judge upped the bail about from $125,000 to $250,000, and required that 15 percent be paid before Simspon could be released from jail.

Glass added that the initial court order to not contact other defendants was clear and she warned that if anything else happened Simpson would be locked up again.

The hearing was at the request of District Attorney David Roger, who filed a motion Friday to revoke Simpson's bail, a clerk for Glass said.

Simpson attorney Gabriel Grasso denied that the former football star violated his bail agreement, in a motion asking that his client be again let out of jail to await trial in his armed robbery case.

Simpson appeared in court Wednesday after spending five nights and four days at the Clark County jail. Police said he has been cooperative after arriving late Friday.

The prosecutor alleged that Simpson tried to get his bail bondsman to take a message to one of his co-defendants in violation of a court order.

"I just want, want C.J. to know that ... I'm tired of this (expletive)," Simpson is quoted as saying in a transcript that was included court documents filed Friday. "Fed up with (expletive) changing what they told me. All right?"

Simpson had been instructed by Las Vegas Justice of the Peace Joe M. Bonaventure in September not to have any contact with anyone involved in the case -- not even by "carrier pigeon."
