Diggs allegedly turned off his headlights and tail lights and drifted between lanes as he continued to flee from the officer.

Eventually as Diggs neared the Overbrook bus station, he lost control of his vehicle and crashed into a jersey barrier, causing the vehicle to roll over.

The Port Authority officer says he saw Diggs get out of the vehicle. Diggs was later found on the opposite side of the jersey barrier.

Diggs allegedly said, “I made a big mistake” before he was taken into custody.

Police say they found five opened cans of Keystone Ice in Diggs’ vehicle.

According to the criminal complaint, Diggs failed field sobriety tests.
