Police say an officer came upon two men engaged in a physical dispute on Stillson Road at the intersection of Black Rock Turnpike in Fairfield Tuesday evening.

They say the officer was able to detain one man who was the primary aggressor, who was identified as Azael Morales-Osorio, 24, and who was armed with a razor blade-style knife.

The second man was treated by responding officers before he was transported to St. Vincent's Medical Center with stab wounds to the abdomen. He is said to be in stable condition.

Morales-Osorio was charged with assault in the first degree and breach of peace. He is being held on $100,000 bond.
