Missing Vic woman may have visited Sydney

A woman missing for more than a month from her Melbourne home may have headed to Sydney, police say.

Yasemo Gunn, 47, was last seen leaving her St Kilda home on Saturday, November 7 and used her bank account at a Sydney CBD ATM several days later but there has been no sign of her since.

Ms Gunn has a medical condition that requires daily medication, and police and her family are concerned for her welfare.
