Three men visiting from Long Island were stabbed yesterday during an early morning brawl in a Midtown building that holds the city’s tourist welcoming center. All three were expected to survive, police said, but some tourists said they were unnerved by the sight of a trail of blood leading down Broadway, and police tape draped across a parking garage at 810 Seventh Ave.

“We just don’t come to New York all that often, and we don’t expect a triple stabbing in our parking garage,” a visitor from Trenton, N.J., John Henderson, 60, said.

Mr. Henderson said he parked his car in the garage the evening before, and that he and his wife had been unable to get it out all morning as police conducted an investigation. Inside the garage, police had marked piles of clothing strewn near a puddle of blood with evidence markers, and dusted nearby cars with fingerprint powder.

Another visitor, Rona Budovitch, 55, who was in town from Wilmington, Del., to see her daughter, was also waiting to get her car out of the garage yesterday.

“I’m generally comfortable in New York City, but this is unsettling,” she said.

A tourist from Columbus, Ohio, Kim Simon, 45, said her main concern was extracting her car from the garage so that her 12-year-old son would be home in time for school today.

“All we want is to get home safe,” she said.

The stabbing took place at around 4 a.m., as a group of men were leaving a nearby bar, Mars 2112, police officials said. All of the victims were 28 years old. One, who was stabbed eight times in the torso, was in critical condition at Weill Cornell Medical Center. Another victim was stabbed six times in the arm and chest, and was in stable condition. The third was stabbed once in the arm, and was released from the hospital.

The city-sponsored visitor center, NYC and Co., opened on time yesterday, a worker who answered the phone there said. He said he had not heard about the stabbing. A spokeswoman for the center, Kimberly Spell, said the parking garage was not accessible from their building.

“The parking garage for the company’s office building is not a part of the visitor’s experience,” she said.

Police were searching for a suspect.
