On Monday, August 3, a 40-year-old woman was walking through Southsea Common near the Pyramids Centre at around 9.45pm, when a man approached her and violently assaulted her.
A man was previously arrested on suspicion of rape.
Police say the man was white with a heavy build and facial hair. He was also described as wearing a dark baseball cap, a dark top with a zip, and a blue surgical facemask.
Two weeks later, police are still investigating the incident, and are renewing their appeal to the public to bring the man to justice.
Acting Detective Inspector Wayne Jackson said: ‘We are two weeks on from this incident and I am looking for information from the local community to tell me who this man is.
‘Were you on Southsea Common two Mondays ago? We are interested to see any photographs people took on the common that evening, as its possible our suspect could be in the background.

‘We want to reassure the community that we are doing all we can to identify this man and keep Portsmouth safe.’
