STAMFORD - The defense attorney for a Stamford man accused of attacking another man with a baseball bat on Wednesday insists his client acted to combat previous threats.

Authorities say the victim, identified as Oscar Hernandez, had harassed the defendant, Rodolfo Calate-Morente, and his wife for three years before the incident. They add that Hernandez rode his bicycle to the couple's home on Aberdeen Street last night, all the while making threats.

Calate-Morente then allegedly attacked Hernandez with the bat, causing head injuries that required emergency surgery.

Calate-Morente's attorney says his client was afraid to speak with police because he and his wife are undocumented.

The prosecutor asked for $500,000 bail, especially since the victim is on a ventilator. He is also suggesting that the case might become a homicide.
