SECTION 1.  Section 47 of chapter 265 of the General Laws, as appearing in the 2008 Official Edition is hereby amended by adding the following 3 paragraphs:-

A person who is placed on probation for any offense listed within the definition of "sex offense", a "sex offense involving a child" or a "sexually violent offense", as defined in section 178C of chapter 6, and who is found to have violated any conditions of release set by the court, shall be guilty of a second and subsequent offense, which shall be punishable by a fine of not more than five thousand dollars, or by imprisonment for not more than two and one-half years in a house of correction, or by both such fine and imprisonment.

Where a defendant has been found in violation of a condition of release under this section, the court may, in addition to the penalties provided for in this section after conviction and any other existing penalties, as an alternative to incarceration and as a condition of probation, require the defendant to wear a global positioning system device, or any comparable device, administered by the commissioner of probation, at all times for the length of his probation. The commissioner of probation, in addition to any other conditions, shall establish defined geographic exclusion zones including, but not limited to, the areas in and around the victim's residence, place of employment and school and other areas defined to minimize the probationer's contact with children, if applicable. If the probationer enters an excluded zone, as defined by the terms of his probation, the probationer's location data shall be immediately transmitted to the police department in the municipality wherein the violation occurred and the commissioner of probation, by telephone, electronic beeper, paging device or other appropriate means. If the commissioner or the probationer's probation officer has probable cause to believe that the probationer has violated this term of his probation, the commissioner or the probationer's probation officer shall arrest the probationer pursuant to section 3 of chapter 279. Otherwise, the commissioner shall cause a notice of surrender to be issued to such probationer.

The fees incurred by installing, maintaining and operating the global positioning system device, or comparable device, shall be paid by the probationer. If an offender establishes his inability to pay such fees, the court may waive them.

SECTION 2.  In cases reviewing the requirement of GPS tracking units for sex offenders convicted prior to 2006, the presiding judge shall make a written finding including the rationale for said finding after a hearing.
