State police at Towanda said they are looking for information on the whereabouts of Jonathan Coleman Butler, 34, of Towanda, who has been charged with attempted aggravated assault on a law enforcement officer, terroristic threats, and fleeing or attempting to elude a police officer. Police have issued an arrest warrant for Butler.

Police said Butler was traveling in a black 2000 Chevrolet Impala at 9:05 p.m. Sept. 22 at the intersection of Borden and McNeal roads in Burlington Township, and a records check showed the vehicle registration was suspended, due to insurance cancellation.

A traffic stop was attempted, but he failed to stop and a police pursuit began. After the pursuit, Butler exited the vehicle and charged toward an officer with a container that had frost and vapors emanating from it, police said.

According to police, it was found to be a cylinder of anhydrous ammonia, which is a chemical commonly used to manufacture methamphetamine. Police said he continued to run toward the officer, threatening to throw the contents of the cylinder on the officer and challenging the officer to shoot him, due to the fact that the container would blow up.

Police said the officer took some steps back for safety, at which time Butler fled into the nearby wooded area. A search was conducted, which yielded negative results.

Anyone with information about his whereabouts is asked to call state police at Towanda at (570) 265-2186 and make reference to Trooper Brandon Allis, or call 1-800-4-PA-TIPS, where a name is not required, just information. An anonymous tip may pay up to $2,000.
