A traffic stop attempt by Metter police Tuesday sparked a three-county motorcycle chase, ending in a crash and the subsequent arrest of a Portal man. Jim Craig Wilkerson, 23, of Portal, refused to stop his motorcycle when Metter officers switched on their blue lights due to his speeding and lack of registration, said Metter police Capt. Robert Shore. Wilkerson had an unidentified female passenger, who was not charged in the incident, he said.
