Four men were arrested during an East End DWI Task Force operation in Riverhead Friday night, authorities said.
The operation included a checkpoint on East Main Street as well as random patrols in the area conducted by the Riverhead, Suffolk County and Quogue police departments, said Riverhead police Lt. David Lessard.
The checkpoint ran from 8 p.m. on Friday night through 4 a.m. Saturday morning and netted four arrests, police said.
Rodney Shorter, 36, of Mattituck, was charged with driving while intoxicated and unlawful possession of marijuana, police said.
Jose Ortega, 34, of Mattituck and Robert Reddick Jr., 22, of Southampton were arrested and charged with driving while intoxicated, police said.
Rodney Trappen, 35, of Aquebogue was also arrested in the police operation and charged with aggravated driving while intoxicated, unlicensed operation of a motor vehicle and unlawful possession of marijuana.
Lt. Lessard said the task force, which began this summer and encompasses police departments across the East End, will conduct an additional operation later this year.
He advised residents to drive safely during the holidays.
