Two days after the death of the 23-year-old gangrape victim, Delhi Police on Monday said it has finalised around 1,000-page chargesheet in connection with the incident and plans to submit it in court on Thursday.

I can't figure out why they have used police as singular. It's one of the prominent newspapers in India. I doubt myself about its usage. Could anyone elucidate it further?
