"Police team raided the woman's house last night. Four Mauser pistols with silencer and 23 live cartridges found concealed in a flour container, were seized," Deputy Commissioner of Police (DCP), Special Branch, Ravindra Singh Pardeshi told reporters.
The action was launched following a tip-off that some weapons have been kept in the house in Seva Dal Nagar in Bhande Plot area, he said.
The woman, identified as Mangala Salunkhe (45), who works as a domestic help, lives in the house with her husband, who is a welder by profession.
"It is suspected that the pistols and the cartridges belong to a local gangster, who must have hidden them in that house," he added.
Further investigation into the case is on, Pardeshi said.
