John de Leon of the Seattle Times reports,

According to police, the victim, a 26-year-old man, was trying to enter his apartment building in the 1600 block of Melrose Avenue at 2:30 a.m. when he was approached by another man, 52. The older man grabbed the victim’s groin and took his wallet.

The victim fought back and two witnesses intervened, separating the two men. The older man then sat down and passed out, possibly suffering a heart attack.
