A suspected jewelry thief was arrested Tuesday night after he was tripped by a bystander while trying to run away from an officer, Lexington police said.

Jamory Christian Dior Russell, 19, is charged with theft, resisting arrest and fleeing and evading an officer. The theft allegedly was orchestrated through the advertising Web site Craigslist.

Lexington police spokeswoman Sherelle Roberts said Russell initially met with a victim who was trying to sell jewelry. Russell had replied to the victim's online advertisement and said he might want to buy the items. When the two met, Russell allegedly grabbed the goods and ran off, she said.

A friend of the victim then contacted the suspect online and told him he had more jewelry to sell. When Russell arrived at the arranged meeting point in the 800 block of North Broadway, the victim was waiting with an officer, Roberts said.

The victim pointed out the suspect to the officer. When the officer tried to speak with Russell, he took off running, she said.

"A short foot pursuit ensued during which an unidentified and unrelated bystander tripped the suspect as he ran past," Roberts said via email.

The officer, Ronald Kornrumpf, caught up with Russell as he tried to stand up. Kornrumpf tackled Russell, resulting in minor injury to both of them, Roberts said.

Russell, who was being held in the Fayette County Detention Center, pleaded not guilty Wednesday afternoon. He was scheduled to return to court July 31.
