This is enforced. That means police cannot arrest on simple complain unless they have good reason . Following the below link

This can atleast save old age parents from going to police station at woo hours.
My question is
What happens after 4 days? when we visit a police station and they do not find my readable reason other than family quarrels? will police continue to investigate.
How police can frame charges and make the arrest happen, when bribed by in-laws?
