A judge in Las Vegas was jumped on and attacked after denying a defendant bail.

Judge Mary Kay Holthus from the Clark County District Court was just about to sentence Deobra Delone Redden when he lunged at her.

Video captured the surprising moment when the convicted criminal leaped out. As he moved quickly towards the judge, Redden was heard saying “nah f*** that b****”.

The judge tried to dodge the attack but Reddon landed on top of her and a marshall and began to brutally beat Holthus, the Daily Mail reported.

During the video, Redden is heard repeatedly punching the judge while yelling abusive language, event as security attempts to hold him back.

Holthus pleads for the man to get off her.

Ironically, the enraged criminal was being sentenced for aggravated battery with substantial bodily harm before he launched his attack, said the Daily Mail.

Judge Holthus was injured in the assault and her condition is being monitored.

The marshall who Redden attacked at the same time had to be taken to hospital.

“We commend the heroic acts of her staff, law enforcement, and all others who subdued the defendant,” Las Vegas District Court said to Channel 13.

“The court remains committed to a safe and secure courthouse and courtrooms.

“We are reviewing all our protocols and will do whatever is necessary to protect the judiciary, the public and our employees.”

Redden’s criminal history involves charges in Nevada and Texas where he has faced charges for battery, robbery, assault, injury to property and coercion, records show.

Previously a judge had demanded Redden undergo a competency determination and he was found to be competent in October.
