There was a black and white foreign crime movie (not sure if it was in Spanish/Italian or some other language)

I think two men (maybe more), possibly gangs committed robbery. Somehow, two women stole the money from them (I think it was a leather briefcase). The men followed them, tracked them down at their home and overcome the women.

The men proceed to torture the women with electricity. I think the women were stripped naked with tape over their mouth laying on the ground with wires attached to their body (maybe breasts) and one man plug in and out the electric plug into the wall. They may have proceeded to rape the women, I’m not sure.

The film was in black and white with no subtitle. I didn’t understand what they were saying. I would like to find it again to see if there is a subbed version.

Thank you!
