It could refer impersonally to the police department in general. I wouldn't call a usage in the singular flat out wrong. Now, "arrives to the farm" which is the other suggested option is another story. Short of some idioms the only time "to" should follow "arrive" is if "to" is part of an infinitive.
I agree with the comments above. The translation here is incorrect. It should be "the police officer/ policemen/ policewomen arrives." Usually, anytime you say "the police" in English, you are referring to "police" as more than one officer. The alternative way to say it, is usually, "the police officer arrives." The "officer" distinguishes it from the plural "police." Policemen and Policewomen work too, as noted above.
