The death toll in the Aligarh hooch tragedy went up to 22 on Saturday, while 28 more people are still in critical condition, an official said.
The official said that seven people have died in the hooch tragedy since Friday night, and added that the condition of 28 people undergoing treatment at the Jawaharlal Nehru Medical College Hospital, AMU, and the Malkhan Singh District Hospital are critical.
Locals fear the death toll can rise further as reports from several villages are still trickling in.
On Friday, Additional District Magistrate (Finance) Vidhan Jaiswal said 15 people had died in villages falling under three separate police stations — Lodha, Khair, and Jawan.
Senior Superintendent of Police (SSP) Kalanidhi Naithani told newspersons on Saturday that five people have been arrested so far, including Anil Chaudhary, the alleged kingpin of the spurious liquor racket.
The police have booked 12 people in three different cases till now. Several raids were carried out in various parts of the district throughout the night and are still continuing.
All the accused have been booked under Gangster Act and National Security Act (NSA) will be invoked against them, according to officials.
A reward of Rs 50,000 each has been announced on the arrest of Rishi Sharma and Vipin Yadav, associates of Anil Chaudhary, the SSP said.
Anil Chaudhary and Rishi Sharma are reported to have strong political connections, and police are looking into their "network", according to an official who did not wish to be named, reported PTI.
The police are also looking into media reports claiming that the illicit liquor was leftover from the huge quantity of spurious liquor which was in circulation during last month's panchayat polls, the report said.
At least five liquor vends have been sealed and a team of senior district officials are checking vends all over the district, the police said.
The authorities have already ordered a magisterial probe and suspended five excise officials.
