MINEOLA - An alleged ticket-writing cutback in Nassau could cost the cash-strapped county.

Nassau?s first deputy police commissioner, Thomas Krumpter, says an internal review found that 10 percent of Nassau's patrol cops -- 160 officers -- have been handing out fewer tickets and parking violations.

He says they offered no valid reason, have been warned and could be further disciplined.

Police officers on the street tell News12 Long Island that morale is low because of wage freezes and department cuts, however, the police union denies there's a deliberate slowdown.

The drop off could cost the county nearly $4 million.
