Washington, Oct 22 (IANS) At least three people were killed while four others suffered injuries after a man started shooting at a beauty spa in Brookfield in the US state of Wisconsin, BBC reported.
According to police, the suspect, identified as Radcliffe Haughton, 45, was later found dead at the scene with a self-inflicted gunshot wound.
Police reached the Azana spa in large numbers after some witnesses said they saw a man with a gun. The shooting began around 3.15 GMT.
Police also discovered what was described as an "improvised explosive device".
Reports say the incident stemmed from a domestic dispute.
Several areas near the spa -- including a shopping centre, a country club and a hospital -- were locked down, as police searched for the suspect.
The four people wounded in the shooting, which took place near a mall in Brookfield, are being treated at Froedtert Hospital in nearby Milwaukee, CNN reported.
Hospital spokeswoman Beth Strohbusch said none of the four victims who arrived there were in critical condition.
