SSP Dharmender Singh also shifted Sahibabad Police Station Officer Brij Mohan to police line in this connection.
According to police, Singh inspected the Sahibabad police station late on Friday and found a minor boy in the lock-up.
"When the SSP gathered details, he found that the boy, who has no criminal record, had been implicated in the Arms Act," said a senior police officer.
On Saturday, Singh suspended Hindon police-post in-charge Dilip Kumar and constable Ravinder Singh for negligence and shifted the station office to police line, the officer added.
