Police in Las Vegas now say the gunman who opened fire from a casino mezzanine Friday morning injured three people before he was tackled by officers and patrons.
Initially, police had reported four people wounded.
None of the injuries is believed to be life-threatening.
Police credit bystanders with stopping the shooter. They say those bystanders included three off-duty out-of-town police officers and two military personnel.
A police lieutenant says, "These are the real heroes."
The shooting broke out a little after midnight at the New York New York hotel-casino.
Police aren't sure yet just how many shots were fired. They say the casino was packed with people who were in town after Independence Day for a holiday weekend.
The man is believed to be in his early 50s and a Las Vegas resident -- not a hotel guest, and not an employee.
