Kevin Nam's Friday night call of nature tied up traffic briefly and garnered him a trespassing charge, Port Authority spokesman Steven Coleman told The Jersey Journal.
Port Authority police say they saw the 21-year-old exit a car traveling in the north tunnel and walk inside a tunnel booth. Police allegedly found him defecating inside, Coleman said.
Coleman said Nam had been in the car with three other passengers about 10 p.m. when he felt sick and told the driver to let him out as they headed through the tunnel, the newspaper said.
The incident forced the closure of the north tunnel for 5 to 10 minutes as police conducted a "standardized security sweep," Coleman said.
The Holland Tunnel runs under the Hudson River connecting the island of Manhattan in New York City with Jersey City, N.J.
