BOSTON (CBS) – A Boston Police Sergeant has been charged with driving drunk after a crash on Interstate 93. Patrick Byrne, 40, of Boston, has been placed on administrative leave.

According to Massachusetts State Police, Byrne was driving a 2016 Ford Explorer on 93 north in Boston around 12:30 a.m. Wednesday when he pulled into the breakdown lane and started turning his hazard lights on and off repeatedly.

That got the attention of a trooper who was on the other side of the highway.

“When the Trooper reached the SUV it was unattended and showed signs of having crashed into a jersey barrier,” State Police spokesman Dave Procopio said in a statement Friday.

Moments later, Byrne walked up to the trooper and they talked. The trooper discovered Byrne had been driving the SUV and gave him a field sobriety test, which he failed, according to State Police.
