Police arrested the man early Tuesday morning in Greenfield after officers found what they believed was cocaine in his car during a traffic stop on Route 2A just before 3 a.m., the Northwestern District Attorney Office said. They did not release the man's name.
While at the Shelburne Falls State Police barracks, the man suffered a medical incident, and responders rushed him to Baystate Medical Center in Springfield, where he died Wednesday morning, the DA's office said.
The Office of the Chief Medical Examiner will perform an autopsy to determine the cause of death.
"Although there are no signs of foul play, the matter is being investigated by Massachusetts State Police Detective Unit attached to the Northwestern District Attorney’s Office," the prosecutor's office said.
