An Upper Brookville man is accused of leading police on a chase that injured a Nassau police officer.
Police say Muhammaddauwd Cheema refused to pull over Saturday night on Northern Boulevard near Glen Cove Road in Greenvale.
Instead, they say the 19-year-old jumped on the Long Island Expressway and hit a highway patrol officer's cruiser.
The officer was treated for neck, back and shoulder injuries.
Police say officers caught up to Cheema on Dickens Avenue in Dix Hills where he was arrested after a brief struggle.
Cheema faces multiple charges, including assault and reckless endangerment.
