A top aide to Holyoke Mayor Alex Morse says a firefighter has resigned as police investigate an allegation of drug possession by at least one member.

 

Rory Casey, Morse's chief of staff, says a firefighter he did not identify resigned Friday.

 

Casey said internal investigations in the fire and police departments have been launched in response to a drug investigation by the Massachusetts State Police. He says the nature and direction of the investigation are developing.

 

A spokeswoman for the State Police did not comment and Fire Chief John Pond did not return calls by the newspaper seeking comment.
