A Thomaston man suffered two skull fractures following an assault Wednesday night,  according to police.

Joseph K. Emerson, 28, of Thomaston, was arrested Dec. 22 and charged with Class B aggravated assault.

Emerson made his initial appearance Thursday, Dec. 23 in the Knox County court on the charge. Justice Robert Murray agreed that Emerson would be held at the Knox County Jail in Rockland pending a January hearing on whether his probation would be revoked.

According to an affidavit filed in the Knox County court, Thomaston police were called to a residence on Sawmill Lane shortly after 6 p.m. as emergency crews were dispatched. The male victim had been struck in the head with a piece of wood, according to the affidavit.

The officer was able to locate Emerson who said that the victim had been the aggressor but acknowledged that the victim had not touched him, according to the affidavit.

The affidavit pointed out the Thomaston officer followed up at Pen Bay Medical Center in Rockport and was told that the victim had two skull fractures and a brain bleed. The hospital was trying to get the man transferred to Maine Medical Center in Portland. The district attorney was contacted because of the slight possibility that the victim could die from his injuries.
