A 26-year-old man has been arrested on suspicion of rape after an alleged attack on a woman in Cowes.
A police spokesman said that at around 6.55am on Saturday, January 12, a man and a woman, who knew each other, were involved in a dispute at the bus stop in Newport Road at the junction of Bellevue Road, Cowes.
"They were seen later heading towards the Bellevue Road area. It's alleged a sexual assault on a woman aged in her 20s took place at an address in Cowes later that day."
Investigating officer Detective Constable Andy Cooper, of Isle of Wight CID, added: "A number of people were waiting at the bus stop at this time and we are keen to speak with anyone who was there.
"The behaviour of the man towards the woman may have attracted the attention of those waiting for the bus, particularly a lady who watched the couple leave the area.
"This witness was described as aged in her 60s and wearing a red coat and had an umbrella."
The 26 year old, from Cowes, has been bailed by police until March 11, pending further inquiries.
