Police are working through a "large number" of suspects in relation to the violent rape of a 62-year-old woman in Nelson on New Year's Day.
Detective Sergeant Ian Langridge said there had been a steady flow of information from the public since police released a computer-generated sketch of the offender from a description provided by the victim.
Mr Langridge said members of the public had nominated a large number of people who fitted that description.
Police were working through the list and continued to have a heightened presence in the area where the attack happened.
The woman was bashed and sexually assaulted in a community garden in the Victory area of Nelson as she worked alone on Tuesday afternoon, in an attack police described as "cowardly and prolonged".
