A drug dealer from Senegal was detained in Italy Wednesday in the death of an American woman found naked and strangled after taking part in a “kinky sex game,” officials said.

The bruised body of Ashley Olsen, 35, was found in her Florence apartment Saturday after her boyfriend had the landlord open the door when she failed to answer her phone.

An autopsy determined she had been strangled with a cord.

The immigrant suspect, whose name wasn’t revealed, was taken into custody after ­investigators obtained DNA from the apartment.
