A driver accused of concealing his history of seizures to get a license and striking and seriously injuring a Denver police officer during a protest over police killings was ordered held on $50,000 bond Thursday.

A judge set the bond as Christopher Booker, 42, briefly appeared in court the day after his arrest.

The Denver Post reported that Booker's public defender told the judge that the bond would be challenged at Booker's next court appearance.

Booker apparently suffered a seizure on Dec. 3 when he struck John Adsit and other officers monitoring a protest of hundreds of high school students. Police say Booker knew his medical condition made him a danger on the road, but investigators found no evidence that he deliberately tried to harm Adsit, who was hospitalized for more than two months.

According to an arrest affidavit, Booker was unresponsive after the crash and later told investigators that he took medication for seizures and had had one less than a month before the December protest.

Police accuse Booker of lying to workers at the state Department of Motor Vehicles at least nine times by denying he suffers seizures. He was arrested on suspicion of felony assault, forgery and attempting to influence a public servant.
