Overview

• Boston police identified the suspect as Alan Musson, 80, of Brookline, and charged him with threat to commit a crime, disorderly conduct, and showing obscene matter to a minor.
• Officers on detail were called around 9:20 p.m. after TD Garden security received complaints from two juvenile girls.
• The girls told police the man turned around during cheering and said, “I will kill you.”
• Police say he then viewed nude photos of men on his phone within the girls’ view, reportedly on the Grindr app, and later acknowledged seeing the images.
• He was escorted out and arrested, his cellphone was seized, and TD Garden upgraded the girls’ seats and provided a security escort as the investigation continues.
