An assistant fire chief with the Carlisle Fire Company was arrested Monday morning for the third time on a charge of driving under the influence.

Delaware State Police spokesman Master Cpl. Gary Fournier said Brennon A. Fountain, 37, was taken into custody at about 1:50 a.m. Sept. 4 near Shawnee Acres.

According to court documents released to the Milford Beacon, a trooper was sent to the area after receiving a report about a vehicle being driven erratically, swerving across the roadway, stopping suddenly and going into reverse.

The responding trooper found the vehicle parked sideways on the road with the engine running.

The trooper banged on the driver’s window, but failed to wake the driver; after opening the door he spotted an open bottle of beer inside. The trooper turned off the ignition, and the driver awoke after he was yelled at. A sobriety investigation followed with a blood alcohol test reading .232, according to the reports.

A computer check showed Fountain had been convicted of driving under the influence in 2004 and again in 2005.

Fountain later was released from custody after posting a $2,000 secured bond.

Fire company public information officer Ryan Knowles said Wednesday Carlisle officials were aware of the arrest.

Fountain was not on duty with the Carlisle company at the time of his arrest, Knowles added. Fire chief Rick Deputy and company President Kevin Donovan are conducting their own investigation, he said.

According to the company’s website, Fountain was named an assistant chief in 2017. He has been a member of the Carlisle company since 1995 and was named Firefighter of the Year at its annual awards banquet earlier this year.
