New Delhi: The Supreme Court today ordered Kerala Police to set up an SIT to probe into allegations of wife-swapping lodged by the estranged wife of a naval officer.

The apex court, which ruled out CBI investigation into the FIR alleging that besides the husband of the woman, four other Navy officers and a spouse of one of them were indulged in wife-swapping in the force, directed the Kerala DGP to set up the SIT headed by a police officer not below the rank of a DIG and conclude the probe in the 2013 FIR "preferably" within three months.
