Vic cops hunt CBD clothes shop 'sex fiend'

Pictures of a man dubbed a "clothing store fiend" have been released after two staff members were sexually assaulted in downtown Melbourne.

Police say the man sexually assaulted two female workers inside the Little Bourke Street store on two occasions in December.

The man had struck up a conversation with a staff member about 7pm on December 18, then allegedly grabbed her and sexually assaulted her in the store.

The next night he had asked another woman for the price of clothing and as she turned around he had allegedly sexually assaulted her.

Police have been told the man smiled at the women in both incidents before running away.

In a third incident he allegedly masturbated through his clothing after talking to a female staff member on March 4.
