ROCHESTER, N.Y. — The Rochester man who police say stabbed a Rochester Police Department officer, hitting her bullet-proof vest, pleaded not guilty at his arraignment Thursday.

Leon Roach, 47, faces numerous charges, including attempted murder.  

Police say officers were called to Louise Street in September for a fight inside a house.

One person was stabbed and another injured after jumping out a window. 

Two more people were trapped upstairs.

Police say when rookie officer Amber Grosch went into the house to secure the scene, Roach allegedly stabbed her in the chest, but her bullet proof vest saved her life.

“They’re doing their best to not only protect themselves but also our community,” said Monroe County District Attorney Christine Callanan. “When an incident like this happens, when they willingly run into a house when there is an individual with a knife, but their first priority is to get to those two people that are upstairs, that speak so much to the service these men and women do for our community.  We take these kinds of the charges very seriously.”

Roach remains in jail without bail. He is scheduled for a hearing next week after he requested a new attorney.
