ROCHELLE PARK - Rochelle Park police say they've tracked down a man they say injured one of their officers in a hit-and-run accident yesterday.

Police in Camden, Del. arrested Lawrence Nelson at a Walmart store this afternoon. Rochelle Park police say they spoke to Nelson's pharmacist in New Jersey who told them Nelson had recently transferred his prescriptions to a pharmacy in Delaware.

When Rochelle Park police called the pharmacy, Nelson was right there at the counter.

He was arrested moments later.

Police say Nelson will be charged as a fugitive from justice and will be extradited back to New Jersey next week.

Authorities say Officer Christopher Rios went to Nelson's Madison Avenue home at around 3 p.m. yesterday to investigate a harassment complaint.

Police say that Rios spoke to Nelson as he sat in his car. Nelson then allegedly put the car in reverse. Rios' hand got caught on the mirror, and he was hit and forced onto the hood of the car. That's when police say Nelson quickly shifted into drive, throwing Rios onto the street.

The officer was taken to Hackensack University Medical Center, where he was treated and released.
