Hamilton police are investigating a late night "business dispute" that sent a man to hospital for stitches.

Police say the incident happened in the lobby of an apartment building at 30 Sanford Avenue just after midnight.

Const. Lorraine Edwards told CBC News that a man and a woman who had no prior connection with each other got into a "business dispute." She could not say exactly what that "business" was, but said it is being investigated.

"They got into a physical altercation," Edwards said. The man was stabbed in the wrist, and was taken to hospital for stitches.

No charges have been laid, but detectives are still investigating, Edwards said.
