Alaska State Troopers arrested a Wasilla man late Friday night who they say assaulted an officer.

Around 10:30, troopers and University Police were called to Constitution Drive in Fairbanks on a report of a man under the influence of controlled substances. 

Officers arrived and found the man, identified as 19-year-old Thomas Barbin, of Wasilla, in the roadway on Farmer's Loop Road. 

AST says Barbin assaulted a trooper and was taken into custody. 

Barbin is facing third- and fourth-degree assault on a police officer charges and troopers say controlled substances were a factor.
