Rank of a SI

This is a sub-inspector rank which is above the assistant sub-inspector of police and below is an inspector. Most of the sub-inspectors are directly recruited into the police force and they do have better educational qualifications than all other lower-ranking police officers.

The specialized units like the Central Armed Reserve Police Force, the State Armed Reserve Police, and the Armed Battalions use this same rank, but generally, all these officers do not have the power to investigate. There are specialist non-investigative officers in Indian law enforcement agencies, like the sub-inspector (band) and the sub-inspector (motor transport).

This is alike to the insignia of the subedar in the Indian Army. While the assistant sub-inspector will only have one (five-point) star, and he also has the red and blue striped ribbon at the outer end of their shoulder straps, this rank is similar to the insignia of a naib subedar in the Indian Army.
