Multiple patrol vehicles were lit on fire and struck by rifle rounds early Wednesday at a northern Michigan police station, authorities said.
The attacker remained at large Wednesday afternoon and was described as a white male wearing camouflage, Michigan State Police said in a statement.
"The suspect should be considered armed and dangerous," police said. "No troopers were in the vehicles when this occurred."
He was last seen driving a silver Honda CR-V, police said.
The incident occurred about 3:30 a.m. at the state police Sault Ste. Marie post.
State police did not immediately respond to a request for additional comment Wednesday afternoon.
"We are asking anyone in the area between 3 Mile Rd and M-80 on M-129 who may have home surveillance cameras to check activity from 3:15am and into the morning for any suspicious activity or the suspect vehicle we have listed above," police said. "Please contact the Sault Post with any info."
