The 26 year old was first targeted in Briarscroft Road.
Separate Attack Linked To Rape
Police investigating the rape of a woman on a canal path by two men believe the suspects also assaulted a man shortly before carrying out the sex attack.
The 32-year-old woman was raped on the path in Clydebank, near Jellicoe Street, between 8.30pm and 9.30pm on Sunday evening.
Police said she had travelled to the area on a bus from Glasgow city centre.
It is thought the men who assaulted her also attacked a male passenger on board the same bus before ejecting him near Scotstoun, officers said.
The first suspect is described as being white, aged in his mid 20s, 5ft 9in to 5ft 10in, of slim build, and with a shaved head. He was wearing a black puffy jacket and dark jeans or joggers.
The second suspect is also white, in his late 20s, 5ft 6in and wore a dark jacket or shirt.
Police Scotland praised the excellent response already received from members of the public and said they want to speak to anyone who was on the bus and witnessed the assault.
It left the St Enoch Centre at 8.15pm on Sunday and travelled via Argyle Street, the Clydeside Expressway and then on to Dumbarton Road, Clydebank, near to where the assault took place.
Detective Inspector Douglas Wilson, of Clydebank CID, said: "We have had an excellent response from the public which has provided valuable information to help us progress this inquiry.
"However, it is vital that we speak to anyone who was travelling on the bus, who witnessed the assault on the man or the behaviour of the suspects towards the woman."
Clydebank CID can be contacted on 101 while Crimestoppers can be reached on 0800 555 111.
