MINEOLA, N.Y. — A Long Island man has been arrested for allegedly threatening to kill a Social Security employee.

Nassau County police say Patrick Finnegan of Port Washington made the threat over the phone on Wednesday.

They say he told the worker he was unhappy with the service he had received and if his complaint was not resolved he would blow her or someone’s brains out.

Police charged Finnegan with making a terrorist threat and aggravated harassment. He’s to be arraigned on Thursday in Hempstead.

It was not immediately known if he had obtained a lawyer.

The employee worked in office in Mineola.
