An Inspector General heading Kochi City: who holds the Commissioner's chair through the Cheranalloor inquiry

Background

The inquiry into the fatal Cheranalloor car crash in Kochi has stayed in the news through this week, with four police personnel of the Cheranalloor station suspended and the case taken over by the Crime Branch, so the change at the top of the city police matters.
R. Nishanthini, an Indian Police Service officer of the 2008 batch, holds the post of Inspector General of Police and Commissioner of Police, Kochi City.
She was moved into the post with immediate effect by a government order, from her earlier charge as Inspector General of Police, South Zone.
She took over from Kaliraj Mahesh Kumar.
In the same order P. Prakash, of the 2004 batch, moved from Inspector General of Police at the State Crime Records Bureau to Inspector General of Police, South Zone.
He also holds additional charge of the State Crime Records Bureau and the Cyber Crimes wing.
Four police personnel attached to the Cheranalloor station had been suspended the previous day over lapses in the investigation into the fatal accident.
The city police chief's post in Kochi is held at the rank of Inspector General, above the Superintendent of Police rank that heads a district force.
