Last week, Indian police arrested at least 70 people suspected of stealing money from people in the United States. The police said people working at a call center in India spoke with the U.S. citizens by telephone. They said the callers acted like they were working for the Internal Revenue Service (IRS), the federal agency that collects income taxes. About 200 police officers raided three buildings in Thane, a community near the city of Mumbai. Police said the workers used phones in those buildings to call the Americans. Parambir Singh is the police commissioner in Thane. He said that about 700 people worked in the buildings, which were open all day and night. Singh said the workers would call Americans and tell them that they owe taxes. If the Americans failed to pay the money immediately, the callers threatened to send police in 30 minutes.
