An unidentified man attending a wedding reception at the Waldorf Astoria Hotel in Manhattan on Saturday accidentally discharged a firearm and injured five people, including one woman who was struck in the head, the police said.

Four people were rushed to hospitals, but their injuries were not severe, the police said.

Emergency medical crews went to the hotel at Park Avenue and 50th Street shortly before 7:30 p.m. and took two people to Bellevue Hospital Center with “minor injuries,” a spokesman for the Fire Department said. Two more were taken to Mt. Sinai St. Luke’s, also with “minor injuries,” and one person refused medical attention at the scene, the spokesman said.

Deputy Chief William Aubry, the commander of Manhattan detectives, said a wedding guest accidentally discharged a firearm in the lobby area of the Waldorf Astoria at around 7:30 p.m. Officials said a bullet ricocheted off the floor and struck one person. Three others were struck by debris such as glass, marble and tile.

The reception was being held in the hotel’s East Terrace, a marbled-floor space that was closed to hotel guests at the time of the shooting. On Saturday night, rows of police tape were strung behind a velvet rope and around a table crowned with a large, ornate spray of white flowers.
