BROOKFIELD, Wis. (AP) -- Deputies searched Sunday for a shooter after multiple people were wounded when someone opened fire at a spa near a suburban Milwaukee shopping mall.
Brookfield police told WTMJ-AM the shooting happened about 11 a.m. Sunday at a spa across the street from the Brookfield Square Mall. The mall and a country club adjacent to the spa were locked down, local media reported.
Calls to police from The Associated Press rang to the Waukesha County Sheriff's Department. A woman who answered the phone there said deputies were looking for an active shooter but did not provide any other information.
Milwaukee FBI spokesman Leonard Peace said its SWAT team, hostage negotiators and others were helping with the response. But he declined to say how many FBI personnel were involved in all or provide details on what had happened.
Robert Schmidt, spokesman for the Bureau of Alcohol, Tobacco, Firearms and Explosives, said it had 10 agents participating.
Beth Strohbusch, a spokeswoman for Froedtert Memorial Hospital, said four shooting victims were taken there, and three more were expected. She said none of the four already received were in critical condition.
WISN-TV reported police were asking people in the mall's parking lot to clear out, because they had set up operations there.
Tactical teams were on the scene, along with at least 20 fire, ambulance and police vehicles. A medical helicopter was on the ground.
The shooting took place at Azana Day Spa, a two-story, 9,000-square-foot building across from the mall in a middle- to upper-class community west of Milwaukee.
It was the second mass shooting in Wisconsin this year. Wade Michael Page, a 40-year-old Army veteran and white supremacist, killed six people and injured three others before fatally shooting himself Aug. 5 at a Sikh temple south of Milwaukee.
The shooting at the mall took place less than a mile from where seven people were killed and four wounded on March 12, 2005, when a gunman opened fire at a Living Church of God service held at a hotel.
