Seven days after a break-out at Campsfield House immigration detention centre, in Kidlington, three escapees remain on the loose.
Police were today continuing the hunt for Abdesalam Tarik Ben, Abdelhak Morid and Mohammed Aref Hosseini.
They were among seven who fled the detention centre in the early hours of last Thursday.
Three were recaptured within a mile of the centre, while a fourth was picked up in Oxford's Botanic Garden.
A spokesman for the UK Borders Agency said: "Public protection remains our number one priority. The UK Borders Agency is considering the lessons that can be learned from the recent incident at Campsfield House and we will continue to liaise with police to locate those missing detainees."
The runaways are not believed to be dangerous, but should not approached, police said.
Anyone with information should call the police on 08458 505505 or Crimestoppers on 0800 555111.
