The anti-corruption squad arrested a contractor allegedly involved in a Rs 42-crore scam in the Madhya Pradesh Excise Department, police said.
The contractor was carrying a reward of Rs 20,000 on information leading to his arrest.
Singh said that Shrivastava had secured the contract of a liquor shop in Indore's MG Road area in lieu of Rs 7.30 crore during financial year 2016-17. But he did not deposit this amount.
He said, "The liquor contractor deposited fake bank challans to the excise department against the payment of this amount, which led to loss to the state exchequer."
The officer said that the police have been investigating 16 liquor contracts given by the Excise Department.
So far, 12 people, including Shrivastava, have been arrested and some of the accused are still on the run.
