Paul Ceglia, indicted on charges of mail fraud and wire fraud, exits federal court in New York, U.S., on Wednesday, Nov. 28, 2012.

Paul Ceglia, the man charged with attempting to defraud Facebook and its founder Mark Zuckerberg, manufactured a device that gave the impression that he was still wearing his ankle bracelet monitor, a law enforcement source told CNBC on Thursday.

Ceglia, who was awaiting trial on May 4, was declared a fugitive by U.S. Marshals after a federal judge issued a warrant for his arrest. The marshals said he is on the run with his wife, two kids and his dog.

"I've been informed that Mr. Ceglia has circumvented his ankle monitor and has vacated his home," U.S. District Judge Vernon Broderick said at a hearing in Manhattan on Tuesday.

Ceglia was out on bail on the condition he would wear the ankle monitor. That bail has since been revoked.

A court hearing has been scheduled for March 24 to address Ceglia's bail.

Defense attorney Gil Messina did not immediately respond to a CNBC request for comment Thursday about the monitoring bracelet. On Monday, he told CNBC he did not know the whereabouts of his client.

Ceglia is accused of fabricating evidence to support his claim to part ownership of the social network. The wood pellet salesman from Wellsville, New York, was charged in 2012 with forging documents to extort Zuckerberg out of a 50 percent stake in Facebook, whose market value on Monday was about $222 billion. He has pleaded not guilty.
