A man who fled police in a stolen Porsche, then two weeks later ran from them on foot before assaulting a policewoman who was trying to arrest him, will serve half a year in jail.The man, Dalton Holton, 24, entered guilty pleas before General Sessions Judge Bill Locke to charges of evading arrest and assault on an officer. He was directed to serve 180 days of an 11-month, 29-day sentence and pay $889 in court costs. Additional charges of evading arrest and violating a bond condition were dismissed as part of the plea bargain.Holton’s issues with the law began last month when he stole his girlfriend’s Porsche from her Spring Street residence.
