Brett Hankison pleaded not guilty Monday to three counts of wanton endangerment.
A grand jury indicted Hankison, who works for the Louisville Metro Police Department, last week.
Jefferson Circuit Judge Ann Bailey Smith also denied Hankison access to a gun.
"People that are in this court charged with offenses involving firearms — I do not allow them to possess any firearm as a condition of their bond," Smith said. "Additionally, the recording of the grand jury proceedings shall be filed in the court file by noon of Wednesday this week."
"A person is guilty of wanton endangerment in the first degree when, under circumstances manifesting extreme indifference to the value of human life, he wantonly engages in conduct which creates a substantial danger of death or serious physical injury to another person," state law says.
