The latest incident happened over the weekend when a 19-year-old girl was attacked at a car park near the Coastguard Station at Quay Street.
Last month two sexual assaults were reported within a space of days, one by a woman who was attacked after taking a lift in a car with three men.
Police have moved to reassure people living in the area.
Chief Superintendent Nigel Grimshaw said: "Local people can be assured that rigorous investigations are ongoing and there is no cause for alarm in the wider community."
The latest attack is believed to have happened at some time between 11pm on Friday and 1.30am on Saturday, and police are appealing for anyone who was there and witnessed suspicious activity surrounding a blue four door car to get in touch.
Officers also want to speak to a woman living in the area who "assisted a distressed female" at around 2am, before feeding her and driving her home to Belfast.
Mr Grimshaw continued: "Police are grateful for the continuing support and cooperation of the local community as they carry out their enquiries."
The previous two incidents happened on 21 and 24 September.
Police want to speak to a man in his early 20s in connection with the first case, which happened in the Quay Street area, and saw a 19-year-old girl attacked on a Saturday night.
In the second incident, a woman was said to have been given a lift by three men in their silver-coloured Ford in the Eisenhower Pier area in the early hours of a Tuesday morning, before being assaulted by one of them at the coastal path near Downshire Road.
"It is unusual for three reports of this nature to come so closely together and we appreciate it is easy for speculation to grow," explained Chief Superintendent Grimshaw.
"However this can lead to inaccuracies and can be unhelpful. We continue to work closely with a range of partner agencies, local businesses, and the community to ensure Bangor continues to be a safe and popular place to visit."
Police said they are following "definite lines of enquiry in relation to each report" and are looking at all available evidence, including CCTV pictures.
