Jorhat police on Wednesday arrested a man on charges of sexually abusing his nine-year-old niece several times.
The accused has been identified as the paternal uncle of the victim and is the elder brother of her father.
He has been booked under Protection of Children from Sexual Offences (POCSO) Act, 2012.
The incident came to light after a lady advocate came to know about the incident on August 26, when the victim was hospitalised because of trauma.
The advocate also lodged an FIR with Jorhat Police Station against the accused.
The advocate later approached a Guwahati-based senior journalist to take over the case after allegations of inactiveness were levelled against the police.
The journalist approached two senior bureaucrats in Dispur and only after their intervention the police swung into action.
The accused uncle was later arrested by the police.
