A repeat offender on probation viciously clobbered a rookie NYPD officer, knocking her down onto a Bronx sidewalk before other cops pounced on him in a wild caught-on-camera arrest Thursday evening.
Ernst Delma, 41, slugged the female officer in the face when she tried to break up an argument between him and a group of kids on a Clason Point street corner, authorities and law enforcement sources said.

Footage captured by a bystander shows the hectic moments after Delma allegedly punched the officer to the ground at about 7:10 p.m. on the corner of Rosedale and Randall Avenues.
Blood streamed from the officer’s face as a bystander helped her up, while her partner rushed the suspect, the video shows.

The injured officer sustained a cut to her lip and was taken to a local hospital in stable condition, police said.
A criminal complaint for Delma identified his alleged victim as Mary Fay — a rookie cop with just eight months on the job.
She has only made five arrests, according to police records. Delma’s felony charges were not among them.
As he was walked out of a Bronx police precinct hours after his arrest, Delma sported a stitched-up swollen eye — and tried to show remorse for his actions.
