More than 150 lines of enquiry are being pursued and 43 people have been identified as 'persons of interest' in the effort to find the man who raped a teenage girl in Gorey.
It happened nearly two weeks ago, and the police say tracking down the perpetrator 'remains a top priority'.
38 calls have been made to police since a poster with an e-fit of the attacker was released last Friday.
A flyer will also be sent to all homes in Grouville and St Martin by the end of this week.
Officers are continuing with house-to-house enquiries covering a larger area.
Two detectives from Guernsey Police have joined one from Devon and Cornwall and around 20 Jersey officers in the investigation.
Anyone who recognises the man in the e-fit, or has any other information about what happened - is asked to call police on 612214 / 612612 as quickly as possible.
Crimestoppers can also be contacted anonymously on 0800 555 111.
