Portland police continue to investigate a stabbing that took place Wednesday night inside an apartment at Bayside Village Apartments at 132 Marginal Way.

Sgt. Jeff Viola said that two men, who are acquainted with each other, got into an argument around 6:30 p.m. One of the men stabbed the other man in the back with a knife.

The victim was transported by ambulance to Maine Medical Center with non-life-threatening injuries, Viola said. The other man was questioned by police but has not been charged.

Viola said police would not release names because no one has been charged. Viola said he did not know what provoked the violence.
