(CNN) -- World Changers Church International in suburban Atlanta became a crime scene Wednesday when a gunman entered and began shooting, killing one, police said.
The golden-domed megachurch, which claims about 30,000 members, is led by well-known prosperity minister Creflo Dollar.
The church has a morning service, but it was not clear whether the service was in progress at the time of the shooting in the chapel, Fulton County police spokeswoman Cpl. Kay Lester said.
Police were searching for the shooter, a man they described as armed and dangerous.
The victim, whose name was not immediately released, died at a hospital.
It was not known if the victim was targeted specifically by the gunman, Lester said.
Dollar has built an international religious empire, with broadcasts of his sermons beamed worldwide and speaking engagements in Europe.
Since he started his ministry in an elementary school cafeteria in 1986, Dollar has earned both praise and criticism.
Supporters say he has preached a message that's financially empowered his parishioners and challenged the idea that Christians should be ashamed to be rich.
Critics call him "Cash-Flow Dollar," and say his message perverts the Gospel.
