A police officer was stabbed in the stomach while responding to a call of a man throwing rocks at cars in Hempstead Village Sunday afternoon, officials said.

Nassau County police officers who were responding to the call trailed the man, described as emotionally troubled, to a home on Emery Street, according to police officials.

Police struggled with the man, who stabbed an emergency services officer in the stomach with a  folding knife.

The 54-year-old officer didn't realize he was stabbed until after the suspect was in custody, officials said.

The officer was taken to Nassau University Medical Center in East Meadow. He is expected to be OK.

The identities of the police officer and the suspect were not immediately made public.
