Women are being urged to take extra care after a string of sex attacks around one area of Nottingham.
All three women were attacked in the same area of Sneinton
Police believe the same man may be responsible for at least four incidents in the Sneinton area over the past three weeks.
The attacks began on 8 December and all three women - two aged 21 and one aged 16 - were walking alone when the assaults happened.
The victims all described the man as Middle Eastern, aged between 20 and 30.
They also said he was wearing a navy blue hooded top with a thick, horizontal stripe across the front.
Det Con John Kerry from Nottinghamshire Police advised women to be sensible when out and about.
"Try not to be out on your own and if you can be, go out with a group," he said.
"Let people know where you're going, especially if you're going to be out in the Sneinton area and if you can, keep a mobile phone with you at all times."
