Jharkhand Inspector-General (Jail) Shailendra Bhusan, accompanied by AIG Tushar Ranjan Gupta, spent around four hours in the jail, police said.
The officials reportedly enquired about why neither the siren blew immediately after the incident nor a warning bell rang.
They also found that CCTV cameras and
video-conferencing systems in the jail were non-functional, police said.
Even the security arrangement outside the jail premises was stated to be inadequate, they said.
An FIR has been registered against 21 and others in connection with the incident.
The administration of West Singhbhum district, under which Chaibasa falls, has beefed up security arrangement in and around the jail premises.
