Hii Jagmal!
The State police department looks into all the Law affairs inside the state. The recruitment is done via SPS, that is, state police services. The minimum eligibile criteria states that the interested Candidate must have completed class 12th and the age limit is from 18 years of age to 25 years of age. So, you can apply as such. Also, If you specify the position you want to achieve or join as, that would help us give specific information.
Hope this helps.
Good luck!
