Melbourne tram pervert has been assaulting peak hour commuters 'for months'

A sexual predator has been assaulting women on Melbourne's crowded trams.

Police say the man gets on the tram in inner-city Carlton during the morning peak hour rush and indecently assaults female commuters before alighting at Melbourne Central.

He has followed the same routine most days since July.

He wears similar clothing every day which is described as a dark grey Adidas jumper, dark coloured track pants and carries a large duffel bag.
