According to our sources, Mel's nanny arrived at the scheduled time of 10:00 AM to pick up the baby for her overnight visit, but Oksana would not answer the door.

We're told as the stand-off continued, things got heated and Mel -- who was not at Oksana's place -- was one step away from calling the cops.  At noon, Oksana finally released the baby to the nanny.

Sources connected with Oksana tell this story -- Lucia was returned late by Mel's nanny earlier in the week so this was a pre-arranged make-good.

As we first reported, Mel's lawyers will ask Judge Scott Gordon on Monday to strip Oksana of custody and overnights, and give her supervised visitation.
