Police think she was murdered after a row with her partner, a fellow asylum seeker identified as Francis Miracle.
The unnamed woman had been at the centre since December 2016.
Police later arrested the suspect, who is said to be a 30-year-old man from Mali, living in northern Italy.
According to reports, he had returned to try to persuade the woman to come to live with him with her children.
Scratch marks were found on his arms.
