A bitter argument over an electric bill resulted in a house call from Collingswood Police Friday night, when one man attacked his roommate in an apartment in the 400 block of Haddon Ave.

At 7:50 p.m. on September 21, officers were dispatched to a private residence to investigate the report of a fight. Upon arrival they made contact with the caller, a 42-year-old male, who appeared to be suffering from multiple stab wounds.

The victim had been stabbed in upper chest and abdomen with a small-bladed kitchen knife. He was transported to Cooper University Hospital in Camden for treatment, and although his condition is unknown at this time, police do not believe his wounds to be life-threatening.

Derek Cool, 34, was arrested and charged with aggravated assault, possession of a weapon, and unlawful possession of a weapon. Cool was remanded to the Camden County Jail in lieu of $75,000 bail.

"This was an isolated incident involving two roommates," said Cpl. Tom Hartshaw of the Collingswood Police Department.
