HOLBROOK - A suspected drug dealer was shot and wounded by an undercover officer during an operation at a Holbrook gas station last night, authorities say.

The Suffolk County District Attorney's Office says the suspect, identified as 21-year-old Nicholas Hansen, shot at members of the Heroin Task Force in the course of a drug sale. One of the officers returned fire, hitting Hansen four times.

The incident took place at the Mobil gas station off of exit 61 along the Long Island Expressway.

Officials say Hansen is expected to recover. He was charged with attempted murder of a police officer, as well as criminal possession of a weapon and cocaine sale charges.
