Boston cop sentenced for tipping off gang members to federal investigation

A Boston police detective who tipped off gang members to an ongoing federal investigation was sentenced to one year of probation and fined $5,000, according to the U.S. Attorney’s office.

Authorities said Brian Smigielski, 43, of Norton was the lead investigator during the early stages of a joint investigation by the Boston Police Department and FBI into the Academy Homes Street Gang. The investigation took place from early 2009 until 2011.

Smigielski became upset when he was ordered to turn over the investigation to the FBI and other department units in late 2009, according to the U.S. Attorney’s office. In the following years, he conspired with the gang members and another department officer to hinder the investigation. Smigielski did so by informing gang members of the FBI’s investigation and warned them of impending arrests, among other actions, authorities said.


Smigielski pleaded guilty in September last year to one count of conspiracy to defraud the United States during the course of a federal investigation.

He was sentenced in federal court on Friday.

An attorney for Smigielski did not immediately return a call seeking comment.
