They are still looking for the man pictured in connection with the incidents.
A suspect first approached a 35-year-old woman from behind and raped her while she was walking home from work in the Plaistow South area of Newham, at 2.40am on Monday, 1 July.
Detectives believe a second attack, where a man made sexual advances towards a woman and robbed her, is linked to the attack. It happened near Leyton Underground Station on Saturday, 6 July at around 3.25am.
Just under an hour later, a 31-year-old woman was raped in Amethyst Road, Waltham Forest. Her property was also stolen.
Today, a fourth incident occurred in Central Park Road, East Ham at around 3.30am.
Another 31-year-old victim was followed by a suspect who threatened to rape her and stole her property.
All four incidents are thought to be connected.
