A man that was arrested in May in connection to a brutal assault plead not guilty to all charges today in Natrona County District Court.

28-year-old Arthur Penrod was arrested in May for a beating that took place outside the Sandbar Lounge in April. The assault involved a pipe and landed a man at the hospital with life threatening skull fractures.

According to police documents, Penrod and another man approached the victim outside the bar stating that, "they needed to talk." Witnesses reported that Penrod then began punching the victim as the other man began hitting the victim in the head with a pipe.

Penrod plead not guilty today to two felony charges of aggravated assault and battery and one misdemeanor charge of battery.

Penrod has two prior felonies, one for aggravated assault in 2003 and another for property damage in 2008. Because of this, if convicted in the current case, he could receive 10-50 years in prison on each of the first two counts and up to 6 months in prison for the third count.

Penrod will be sentenced at a later date and will remain in the Natrona County Detention Center on a 100,000 dollar bond.
