Two Springfield men authorities suspect are behind a "major crime spree" in western Massachusetts were caught selling bags of heroin stamped with Republican presidential candidate Donald Trump's name and face, police said.

Suspects Mark Hunter, 55, and Seneca Johnson, 39, have been held since a drug raid Wednesday. Today, detectives from the Springfield Police Department's Major Crime Unit announced they have since tied the duo to four bank robberies and the armed carjacking of an ATM company driver.

Department spokesman Sgt. John Delaney said search warrants executed last week at homes on Westford Circle and Searle Place yielded a large quantity of packaged heroin with "Donald Trump" stamped on the bags. The "Donald Trump" heroin bags have become popular in the northeast, Delaney said.

As a result of the ongoing investigation led by Captains Trent Duda and Rupert Daniel, Delaney said Hunter and Johnson now face additional charges of armed robbery and armed robbery while masked for four bank holdups in Springfield and Orchard dating back to February as well as armed carjacking with a firearm for the April 29 ambush of a serviceman delivering cash to ATMs across Springfield whose van was stolen.The ATM serviceman was not hurt, but shaken, police said.

In a separate case, a New Hampshire woman was charged last month with dealing heroin also stamped with Trump's name.
