Nassau University Medical Center doctors say the police officer injured by an alleged drunken driver is steadily improving.

Nassau Police Officer Kenneth Baribault, 30, was rear-ended while sitting in his patrol car Sunday. He underwent pelvic surgery and is no longer running a fever, doctors say. However, Baribault remains in critical condition.

Nassau County Executive Tom Suozzi and fellow officers visited Baribault at his bedside Thursday. Nassau Police Commissioner Lawrence Mulvey says the outpouring of support from residents, officials and cops has been remarkable.

The alleged drunken driver who hit Baribault?s patrol car, 27-year-old Raheim Graffin, waived a court appearance Thursday. He faces charges of vehicular assault, reckless driving and DUI. Graffin?s attorney, Anthony Colleiuori, describes his client as ?despondent? over Baribault?s injuries. Colleiuori says he almost asked for his client to be on special watch while in jail.

Graffin is being held on $100,000 cash bail and is due back in court on June 5.
