FIR and Investigation in 498a

Respected Ld Members,

In 498a are there any orders/ciruclars/ that,

POLICE can Reg FIR and do investigation and also can come to the house and take the

accused to the POLICE STATION without any instruction from the DCP/ACP/Superiors.

Luckily in this instant case accused did not go to the POLICE station but asked permission that, he  will come later

But, i request you to  please tell the correct procedure[with CrPC code] on this issue

thanking every one in advance
