[17] On 16 August 2019, Singh was booked under the Unlawful Activities (Prevention) Act after the police took possession of an AK-47 rifle, a magazine, live cartridges and two hand grenades following a raid on his ancestral home in Ladma village of Patna district.

On 14 August 2024 Patna High Court acquitted Anant Singh in case of illegal arms act for which he was serving 10 years sentence from 2022.

The fortune of Singh turned when Nitish Kumar, decided to nominate him as his candidate on the ticket of Janata Dal (United) from the Mokama constituency.

It was considered as paradoxical by a section of media that Kumar who vowed to end 'criminalisation of politics' was backing such a person against whom charges of serious cognisable offences were lodged.

But, amidst criticism and counter statements Singh managed to win from Mokama seat due to support of his castemen as well as the wave of Nitish Kumar.

[20] Singh's activities dragged the country's attention when in 2007 he was reported to have two journalists from NDTV 24x7 and ANI News as hostages in his official bungalow.

It was reported that they had been there to interview Singh upon his involvement in murder and molestation of a woman called Reshma Khatoon whose body was recovered in a sack near the capital.

The political protection given to Singh and another gangster named Sunil Pandey by the ruling government was aimed at mobilisation of Bhumihar caste.

As per news reports, the four youths were kidnapped and assaulted allegedly by the goons of Singh and one of them named Puttus Yadav was killed brutally.
