A Sergeant with the Middlesex Sheriff’s Department has been arraigned on drug charges after allegedly receiving cocaine and money from an undercover state trooper, Middlesex District Attorney Gerry Leone informed the public today.

Michael Dell’Isola, 51, of Somerville, was arraigned today in Woburn District Court on the charge of trafficking cocaine. Woburn District Court Judge Paul Yee ordered the defendant held on $1,000 cash bail with the condition that he stays away from the Sheriff’s Department.

His next court date is June 8 for a probable cause hearing.

According to authorities, in April, Massachusetts State Police assigned to the Middlesex District Attorney’s Office received information regarding the defendant’s illegal actions. Based on this information, the State Police began an investigation which concluded yesterday with an undercover state trooper delivering cocaine and $500 to the defendant in Woburn. The defendant is alleged to have accepted the illegal narcotics and money and was arrested on the scene. He was transported to the Medford State Police Barracks for booking.

These charges are allegations, and the defendant is presumed innocent until proven guilty.

The prosecutor assigned to the case is Assistant District Attorney John Verner, Chief of the office’s PACT Unit. This case is being investigated by Massachusetts State Police assigned to the Middlesex District Attorney’s Office and investigators from the Middlesex Sheriff’s Department.

The Middlesex District Attorney’s PACT Unit, established when District Attorney Leone took office, is dedicated to the investigation and prosecution of cases of public protection (including narcotics and organized crime), anti-terrorism, corruption, and technology. The Unit has investigated and prosecuted multiple cases of alleged public corruption and organized crime, including:

* Commonwealth vs. Peter Limone, et al, in which more than 140 indictments were brought against 20 men in connection with their involvement in organized crime activities.
* Commonwealth vs. John Buonomo, in which the defendant, the former Register of Probate, pled guilty to the theft of thousands of dollars of public monies.
* Commonwealth vs. Richard Stewart and Joseph Falzone, in which the defendants, two Department of Conservation and Recreation employees, pled guilty to the theft of more than 2000 feet of cast-iron coping from the Longfellow Bridge and selling it to a scrap yard for approximately $12,000.
* Commonwealth vs. David Annis, a Lowell police officer found guilty on extortion and other charges.
* Commonwealth vs. Paul Camilli, the former Superintendent of Public Works in the town of Maynard, found guilty of soliciting cash payments from a private developer in exchange for relaxing the permitting and inspection process for a construction project.
